A mechanism is one in which one of the links of a kinematic chain is fixed. Different mechanisms can be obtained by fixing different links of the same kinematic chain. These are called as inversions of the mechanism. By changing the fixed link, the number of mechanisms which can be obtained is equal to the number of links. Excepting the original mechanism, all other mechanisms will be known as inversions of original mechanism. The inversion of a mechanism does not change the motion of its links relative to each other.

Inversion of Four bar Mechanism (Project Based Learning)

This mechanism is used for converting rotary motion into a reciprocating motion. The inversion is obtained by fixing either the link 1 or link 3. In this, link 1 is fixed. When the link 2 (which corresponds to crank) rotates about B as center, the link 4 (which corresponds to a frame) reciprocates.

Inversion of Single Slider Crank Mechanism (Project Based Learning)

"The Psychology of the students were tested through this process .Thematic Appreciation Tests are meant to evoke an involuntary display of one’s subconscious There is no standardization for evaluating one’s TAT responses; each evaluation is completely subjective because each response is unique "

Our faculty community continuously encourages the students to learn and help creating a demo model, which gives them hands on experience and practical learning.

industrial

case study

Naturally, students are more inductive than deductive, they learn better from examples than from logic. So, we believe the use of case studies is a very effective classroom technique. Students will be provided with an industrial case study linked with the concept or subject, where the students got to explore how their learning are applied in the real world situations. This helps the students to actively engage in figuring out the principles from the examples.

Objective:

This Case study is about failing of thermocouples in ethylene cracking plant and has been taken from a Chemical manufacturing plant at south Louisiana. The problem on failing of thermocouples was identified by Thermosensors Corporation.



Problem Statement:The Thermocouples used in the effluent stream of ethylene cracking furnaces were failing frequently and drifting as much as 80° F, resulting in production slowdowns and outages. During these outages, a steam air decoke process occurred, so thermocouples and thermowells had to be inspected and failed assemblies replaced.



Solution:It is clear from the problem statement that thermocouples used now in the ethylene cracking furnaces are failing frequently and hence there is a need to replace the thermocouples and redesign the thermowells for increasing the efficiency of the plant.


There are two main types of thermocouples, base metal thermocouples and noble metal thermocouples. The base metal thermocouples are made of materials like nickel, iron and copper. Base metal thermocouples will have high sensitivity and they are less expensive. The Noble metal thermocouples are made of noble metals like platinum and rhodium. They are highly expensive, but they have ability to withstand high temperature and measure high range of temperatures.


Analysing the various types of thermocouples and taking into account the cost of the thermocouple, their withstanding capacity and measurement range it was found that both Type K and Type N thermocouples suits the requirements. Though Type N thermocouple withstands high temperature capacity of 1300 ºC and is slightly expensive, it is not best suited for this particular application. Type K thermocouples are not expensive and they can withstand the temperature of 1260ºC which is higher than the ethylene cracking furnace temperature. This Type K thermocouple will be best suited for our application and it is found that the run time of the furnace has been increased by five times after replacement. Thus the customer experienced high reliability and accuracy of temperature readings after redesign and replacement.


Objective:

This Case study is about usage of zero speed sensors in Industrial Environments and is a real time problem in most of the manufacturing industries. The Inability of the Hall Effect base zero speed sensors to sense the speed of the gears has been clearly pointed out in this case study and has been taken from Motion sensors Inc, North California.



Problem Statement:A zero speed sensor was installed to sense the rotation of a gear in a piece of heavy equipment. The location of the installation exposed the speed sensor to metal shavings and debris that were present in the environment. The existing speed sensor used a back biased Hall Effect technology which incorporated the use of a magnet. The metal debris was attracted to the magnet and accumulated around the tip of the speed sensor, over time affecting the ability of the sensor to accurately distinguish the teeth of the spinning gear.



Solution:In most of the Manufacturing Industries metal debris and shavings will be present in the environment due to the metal cutting processes. The metal particles get attracted to the hall effect sensors due to the presence of magnet inside them. During the process of continuous speed sensing, the tip of the sensor is completely covered by metal particles thereby making it incapable to sense the rotation of the gear. Thus the efficiency of the sensor is drastically reduced.


The above problem can be solved in the Industry by replacing the current sensor with RF speed sensor. In the RF speed sensor, due to the absence of magnet the metal shavings and debris are not attracted towards the tip thereby improving its speed sensing ability. It effectively removed the strong magnetic field eliminating the performance issue.

In this case study, we have discussed an average precipitation of 1170 mm rain fall and the classification of rivers in India. Further, we find the solution for water resources problems.

Mathematics is used to solve many real-world problems in industry, the physical sciences, life sciences, economics etc. This presentation is then mathematically manipulated to provide some useful information. Finally, the knowledge gained from this information should be translated into an action for the system, situation, or problem at hand.

A case study of the Tabriz Tractor Manufacturing Company (TTMC) that demonstrates how GT can be applied in metal forging operations and (2) present a coding system based on the hybrid coding structure designed for the TTMC’s forging operations. In addition to these contributions, we present a Visual Basic computer software developed to classify parts in the actual forging operations of the TTMC, based on the design hybrid coding system. This classification and coding system, while developed specifically for the TTMC, should work with all forging operations. The parts classification and coding system designed for implementing the GT in the forging operation of the TTMC is described. It is difficult to adopt existing systems for industries or operations other than the forging operations of the heavy equipment industry because each industry (and the operations) has a different priority when grouping the parts. Therefore, a new classification and coding system is developed to consider, explicitly, the specific parts parameters and the production process specifications of the TTMC’s forging operation. While the system is developed specifically for the TTMC’s forging operation, it should be applicable to all forging operations in similar industries.The first digit of the above code can take the values 1, 2, 3 or 4, based on the following rules on a part’s general geometric shape.The second digit is defined following the hierarchical structure and is directly related to the first digit (general geometric shape). Subsequent digits (digits 3 to 6) follow a chain structure and are coded using more detailed geometrical specifications. The decision rules and the coding values are outlined in the Appendix. The implementation of the GT can decrease the activities and lead time relating to part design, improve company responsiveness to customer orders and streaming production processes. The implementation of a GT system that integrates part data, GT codes, operations process plans and CAD management features, as presented in this paper, can reduce repetitive activities in engineering by allowing the designs and processing plans of existing parts to be reused for parts with similar features. By reusing the existing design and plans, the forging operations can be more efficiently standardized, and the need for a production feasibility analysis is reduced. Thus, lead to a greater process reliability and production efficiency. This is very beneficial for the TTMC’s forging operations. Furthermore, such an integrated system retains and improves the organisational knowledge and memory, because part designs and processing plans can be shared more readily and such information remains with the company when experienced technical staffs leave the company.

In order to improve the perceived sound quality of diesel engines, Isuzu cooperated with Brüel & Kjær to develop mapping of Sound Quality metrics, where noise sources can be identified based on their sound character using perception-based metrics such as loudness, sharpness and roughness. Together, they also developed a new impulsiveness algorithm to clearly identify the source of impulsive noise in diesel engines. The result of the Isuzu/Brüel & Kjær project is now the world’s first commercially available sound quality metrics mapping software for beamforming and Statistically Optimal Near-field Acoustic Holography (SONAH) systems.In recent years, environmental issues have placed emphasis on vehicle emission and vehicle noise including improved engine noise performance. It is becoming increasingly important not just to reduce the radiated sound pressure, but also to improve the sound quality of vehicles for the comfort of both passengers and local residents. Isuzu regards sound quality as a key selling point and differentiatorDiesel engines make a characteristic noise known as diesel clatter, diesel nailing, or diesel knock. This is caused largely by the sudden combustion of fuel that has already evaporated when combustion starts. Although unavoidable, this sound is not desirable and it is notoriously difficult to identify precisely where the sound is coming from. Traditional microphone array techniques, such as beamforming and near-field acoustic holography (NAH) localise noise sources based on physical quantities such as sound pressure and sound intensity. However, other sources may have higher values of sound quality metrics, so the objective data in the contour plot may not accurately reflect one’s subjective perception. For example, improving the perceived sound quality of diesel engines may require the identification of noise sources emitting impulsive or rough sounds rather than having higher sound pressure level. For this reason, Isuzu got together with Brüel & Kjær to develop mapping of Sound Quality metrics, where noise sources can be identified based on their sound character using perception-based metrics such as loudness, sharpness and roughness. Together, they also developed a new impulsiveness algorithm to clearly identify the source of impulsive noise in diesel engines.As a result of the cooperation between Brüel & Kjær and Isuzu, mapping of Sound Quality metrics has been implemented in PULSE Beamforming Type 8608 and PULSE Acoustic Holography Type 8607 and is the world’s first commercially available sound quality metrics mapping software for beamforming and SONAH systems – a first class example of how Brüel & Kjær and one of its key customers worked together to develop cutting edge technology for the automotive industry.

The aim of this work is to utilize the heat energy wasted in exhaust gas of an internal combustion engine of low capacity for desalination using a submerged horizontal tube straight pass evaporator and a condensing unit, without the aid of any external energy used for pumping system. In this work a horizontal tube straight pass evaporator and water cooled condenser for condensing the evaporated steam were designed and fabricated. The experiments were conducted in a 5 hp diesel engine to analyze the performance of the submerged horizontal tube straight pass evaporator (SHTE) under various load conditions. It is evident that 3.0 l/h of saline water can be desalinated from the engine exhaust gas, without affecting the performance of the engine. More over nearly 24 l of water is heated, up to 60 °C in the condenser unit. By utilizing the heat energy in condenser water in addition to waste exhaust gas heat energy the overall efficiency of the system is enhanced and thermal pollution is also reduced considerably.

In the present case study, the methodology of designing and machining the femoral component of total knee replacement using a 3-axis Computer Numerical Control (CNC) machine is presented, and then, the results of the machining process, as well as the evaluation of implant surface quality are discussed in detail. At first, a preliminary design of the components of the knee implant is performed and the planning for the production of the femoral component is implemented in Computed Aided Manufacturing (CAM) software. Machining of complex, “sculptured” surfaces is important in various industries such as automotive, aerospace and optical components industry, as well as bioengineering. One of the main challenges concerning the machining of such surfaces is the reduction of machining time, as it is considerably difficult to achieve the required dimensional accuracy and surface quality. Apart from the use of cutting tools with special geometry, the machining strategy needs to be carefully planned in order to achieve the desired geometrical features and suitable process parameters are required to be determined as well. Thus, all of these tasks need to be appropriately addressed by the use of CAM software in order to perform the machining process of the femoral component. Then, three femoral components are machined under different process conditions and the surface quality is evaluated in terms of surface roughness. Analysis of the results indicated the appropriate process conditions for each part of the implant surface and led to the determination of optimum machining strategy for the finishing stage. The design and manufacturing of medical implants constitutes an active and highly important field of research, both from a medical and an engineering point of view. From an engineering aspect, the machining of implants is undoubtedly challenging due to the complex shape of the implants and the associated restrictive geometrical and dimensional requirements. Furthermore, it is crucial to ensure that the surface integrity of the implant is not severely affected, in order for the implant to be durable and wear resistant.

This case study focuses on the study of virtual reality in the assistance of CNC machine tool demonstration and exhibition. A commercial CNC machine tool was used in this study to illustrate the effectiveness and usability of using virtual reality for an exhibition. The adopted CNC machine tool is a large and heavy mill-turn machine with the width up to eleven meters and weighted about 35 tons. A head-mounted display (HMD) was attached to the developed VR CNC machine tool for the immersion viewing. A user can see around the 3D scene of the large mill-turn machine and the operation of the virtual CNC machine can be actuated by bare hand. Coolant was added to demonstrate more realistic operation while collision detection function was also added to remind the operator. This case study has shown that young engineers and/or students are very impressed by the VR-based demonstration while elder persons could not adapt themselves easily to the VR-based scene because of eyesight issues. However, virtual reality has successfully being adopted and integrated with the CNC machine tool in an international show. Another machine tool on laser-assisted milling machine motion simulation has also been successfully conducted to show the expandability of the VR based technology. One can conclude that VR will be adopted and paid more and more attention in the future in helping CNC machine tool promotion. Exhibition and demonstration are generally used in the promotion and sale-assistance of manufactured products. However, the transportation cost of the real goods from the vender factory to the exposition venue is generally expensive for huge and heavy commodity. With the advancement of computing, graphics, mobile apps, and mobile hardware the 3D visibility technology is getting more and more popular to be adopted in visual-assisted communication such as amusement games. Virtual reality (VR) technology is therefore used in emulating expensive small and/or huge and heavy equipment. Virtual reality can be characterized as 3D extension with Immersion, Interaction and Imagination.

Design and Fabrication of Alpha Stirling Engine

The Stirling Engines being researched here are the acoustic engines and the Alpha Stirling Engine. The acoustic engine was built and the alpha engine was designed. The idea in the beginning was to improve each engine based around efficiency. Theoretically, each design could be improved based on different factors. The re generator becomes a big factor in both engines around the thermal efficiency loss. A successful re-generator limits the amount of thermal energy loss while controlling its dead volume. Any form of regeneration limits the loss of heat therefore optimizing any engine performance. A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. It is a closed-cycle regenerative heat engine with a permanently gaseous working fluid. Stirling engines have a high efficiency compared to internal combustion engines. being able to reach 50% efficiency.

Design and Fabrication of LPG Based Engine

With the advent of time an increased exhort to make environment sustainable has been a driving force for many researchers. There has been a lot of pragmatic work captured under various initiatives and schemes where the thrust has always been on securing a cleaner emission. In order to strive for cleaner emissions with higher efficiency, experimentation has delivered positive results. Transcending from petrol and diesel, the inclination is more on leading to fuels which are not only efficient like the conventional ones but at the same time will yield less harmful elements post combustion in engines. Application of alternative fuels like Liquid Petroleum Gas (LPG) and Compressed Natural Gas (CNG) are gaining in prominence now since they are not only less harmful but also deliver equivalent efficiency. This paper would go on to showcase an experiment that achieved a prominent result of LPG usage over petrol in a Spark Ignition (SI) engine.

Digital Patch Adhesion Tester

The adhesive bond strength between a skin and a patch surface has been studied using a specially designed adhesion testing apparatus. The adhesion has been taken as the force requires removing the patches from unit area of the skin surface and has been shown to be dependent on the compression pressure used to prepare the patches and on changes in the film formulation. Adhesion problems are usually not identified until prolonged compression rings are studied in the end of the drug development process. During patches manufacturing, adhesion problems encountered are usually addressed by statistically designed experiments based on experience.

The improved bearing puller is an attempt that because of its unique geometry and design, will facilitate the easy and rapid removal of blind press fit bearings with little or no resultant damage to the bearing housing. For removing a bearing or axle bushing from an axle, a hydraulic puller comprising a pawl assembly mounted on a hydraulic pipe, an oil container attached to the hydraulic pipe at the top, a movable rod movable fastened in the hydraulic pipe at the bottom, a piston rod controlled by a hand lever to squeeze a hydraulic oil out of the oil container for moving the movable rod, and a spring to automatically push the movable rod back to its original position.

Design and Fabrication of Cantilever Beam to Measure Strain

At present it is very difficult to calculate the strain produced in a cantilever beam. We have to use many formulas to calculate the strain produced. Hence this project deals with the design and fabrication of cantilever beam with strain gauge setup to measure strain. A cantilever beam is fixed to a support and known load is applied at the free end to produce vibration in the beam. A strain gauge is attached to the beam and the strain gauge is interfaced to the micro controller. Strain is displayed in the strain gauge when a known load is applied at the free end.
