PROJECT WORK DETAILS

Diploma in Mechanical Engineering:

Project: Electro – Magnetic Braking System.

Fabrication of Electro – Magnetic Braking System also called electro-

mechanical brakes or EM brakes slow or stop motion using electromagnetic force to apply

mechanical resistance (friction). Both electromagnetic brakes and eddy current brakes use

electromagnetic force but electromagnetic brakes ultimately depend on friction and eddy current

brakes use magnetic force directly. This was fabricated to make use of it in areas where both

partially applied brakes (in cranes) and fully-applied brakes are required in a single machine.

Trams and trains use electromagnetic track brakes where the braking element is pressed by

magnetic force to the rail. They are distinguished from mechanical track brakes, where the

braking element is mechanically pressed on the rail. Electric motors in industrial and robotic

applications also employ electromagnetic brakes

B. Tech in Mechanical Engineering:

Project: Automatic Temperature Controller with Cooling system.

It is the refrigeration system which automatically controls the temperature of small room

(10 X 12 feet) maintaining Human comfort by use of Temperature Controller.

This Refrigeration System posses a Sensor ( Ultrasonic type Proximity sensor ), which is capable

of sensing small changes in room temperature thus activating the Temperature controller to run

the blower and pump of Cooler and thus the Sensor Technology enables to provide sufficient

Human Comfort.

This system is portable in size and is simple in construction. This is provided with a temperature

controller which is used for adjusting required temperature. This system is noise-less in operation

and its maintenance cost is also less. Further, this can be run un-interruptedly by making use of a

Solar Panel (Auto-tracking System), which rotates with the movement of the sun.

M. E. ( Engineering Design ) in Mechanical Engineering:

Project: Notch strength prediction of Glass-Fiber Reinforced Polymers (GFRP’s) using Design

of Experiments

The objective of this project is to determine the Notch strength of GFRP’s under different

Volume fractions of fiber (40%, 45% and 50%), fiber orientations (0 0, 450 and 900) and Notch

depths (1, 2 and 3 mm) considered as variable parameters.

Fiber reinforced Polymer composites are finding wide applications in numerous structures

of aircraft and spacecraft, subsea installation protection cover, large wind turbine blades as well

as other cladding situations. Study on Notched strength in Glass fiber reinforced polymers is used

to express the fracture behavior of composite specimen. The degradation of strength of composite

materials in presence of notch must be understood precisely under any situation for the wider

application and is of greater importance.

This work is focused to study the effect of notch by varying fiber content and its

orientation on the tensile properties and mechanical stresses that can occur in structural polymeric

composites. In this work, ASTM D638 standard (165X20X3 mm) is used for fabrication to study

the response of notch strength factors viz. Volume fraction of fiber, fiber orientation and notch

depth. Based on the three factors and three level considered for study, L9 orthogonal array was

selected to conduct the experiment. With these three variable parameters, a full factorial design

with 27 test cases is obtained and by using L9 orthogonal array the number of test cases is

reduced to nine experiments.

These fabricated composite specimens are to be analyzed using ANSYS software by

giving input property values (obtained from tensile testing) and is to be compared with test results

for validation.
