Mild steel or wrought iron shaft are present with the lengths varying from 6 to 10 meters to make handy and easy for transportation. The practice shafts in engineering with large lengths are needed for transmission of the torque that is formed by joining two or more shafts for required length. The joining of shafts is accomplished by a device called coupling.

 Requirements of a good shaft coupling include the following notes which are, it must easy to connect or disconnect, must transmission of full energy from source shaft to destination shaft without any losses, must hold the shafts in exact placement, and must reduce the transmit shock burdens from source shaft to destination shaft.

 The assortment of gear couplings is present with many configurations which help to couple two shafts. The gear coupling is customized to save power and bearing breakdown.

 There are many couplings such as precision coupling, gear coupling, flexible coupling, jaw coupling, grid coupling, multi beam coupling, KTR coupling, tyre coupling, and universal coupling etc.

 Conclusion:

This Mechanical Final Year Project on Design and Fabrication of Tyre Coupling concludes that there are different couplings which are used to join shafts in various ways.

The main aim of this PROJECT REPORT ON DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM is Cryogenics.

Cryogenics is the study of low temperature which means the entire phenomenon locates below -150°C or 123K. Cryogenic engineering is the design and development of systems and components to maintain, produce, or utilize low temperatures. The systems produce the refrigeration power at low temperature.

There is a strong requirement of cryocoolers for many applications. Infrared detectors, thermal imagers and night vision devices require form of cryogenic cooling for military purpose. The chips of semiconductors cryogenic cooling in the electronics improve the performance drastically to reduce the thermal noises. These are important part of the ultra clean high vacuum cryopumps utilized for high reliability in the manufacturing of semiconductors.

Cryocoolers are required for cryogenic surgery and conservation in the areas of medicine and cryobiology. These are very reasonable price, flexible in all weather conditions and high security is the important factor. Cryogenic temperatures are maintained and achieved with one or more refrigerating units called cryocoolers.

Gifford and Longsworth observed the cooling effect with a pulsating pressure inside the gas. It marks the promising cryogenic refrigerators called pulse tube refrigerator (PTR). The pulse tube system is the most researched project in the field of cryogenic refrigeration because of the absence of moving parts in the cold temperature region and simplicity and enhanced reliability. The pulse tube refrigerator used for cooling infrared detectors for missiles, military aircrafts, tanks, and night

Conclusion:

An orifice pulse tube refrigerator performance and characteristics are simulated successfully with a numerical method on a personal computer. Obtained input parameters give an optimum refrigeration power which avoids necessary laborious manual calculations.

The Mechanical Final Year Project Report is about the system to freeze for many applications. The kind of cooling is utilized to store fruits but unfit for fish industries. Further, there are many reasonable vegetative microorganisms discovered in food which have decreased by refrigeration when high freezing is utilized. The common freezers are unable to manage with great rate of cooling. The challenge of rapid freezing has increased efficient storage with the progress of plate freezer.

The plate kind evaporators are employed in banks or in single. The plates possibly manifold to pass the refrigerant parallel or connected for flow in the serial way. Plate evaporators are beneficial for the purpose of liquid freezing installation.

This Design & Fabrication of Plate Freezer project is about the plate freezer designed with two plates linked in parallel with freezing load of 0.335 KW. The tube is installed among two metal plates and plates are brazed together at the border which results in plate surface evaporators.

The common food protection is done by storing the food in the chambers possessing the evaporator coils surrounding it. The chamber is insulated with casing around it. The heat from the food to the chamber surface is transferred through the air space. The freezing rate takes lot of time and is low because of the fact that air is a bad conductor of heat. The freezing rate is incremented with the freezer.

 Conclusion:

The Engineering Mechanical Student Project held for the freezing system described the deficiency of the refrigerant the flow rate through the top plate. The system can be utilized at various temperatures based on our requirements.

The car suspension maximizes the friction between the road surface and the tires to give steering stability with good handling which ensure soothe of the passengers. This article explores about the working of car suspensions and design of suspensions in the future.

 If a road is flat then suspensions are not necessary. As per Newton’s laws of motion, force has both magnitude and direction. The magnitude depends on striking of wheel to a giant bump or a tiny speck and the car wheels experience vertical acceleration when it passes over a bump.

 The study of the forces on a moving car is known as vehicle dynamics and many automobile engineers determine the dynamics of a moving car from two concepts such as Ride, the car’s ability to comfort a bumpy road and Handling, the car’s ability to safely brake, accelerate, and corner.

 The suspension of a car is the part of the chassis that comprises important systems. This system includes The frame is a structural load-carrying component to support the car’s engine and body, The suspension system is a setup to support weight, absorbs and dampens shock and also helps maintain tire contact, The steering system is a mechanism which guides and directs the vehicle, The tires and wheels are components to have grip and/or friction with the road.

There are suspensions used in the vehicles which are Dependent Front Suspensions, Independent Front Suspensions, Dependent Rear Suspensions, and Independent Rear Suspensions.

Conclusion:

This DESIGN & FABRICATION OF SUSPENSION SYSTEMS Mech Project Report article concludes on the working of car suspensions and design of suspensions which maximize the friction between the road surface and the tires for the comfort of passengers.
