DESIGN AND FEA ANALYSIS OF BREAKING SYSTEM
ABSTRACT
With the increasing technological development in the area of motors, heavy duty vehicles have been suffering an increase in size and capacity. Friction breaks are decelerate a vehicle by transforming the kinetic energy of the vehicle to heat via friction and dissipating that heat to the surroundings, which produces excessive heat on lining surface. This shows increase in frictional area will definitely reduce the load on breaks by sharing the energy of the vehicles. So the above mentioned factor is taken in to account and finally reduction in inertia forces on rotating shaft by providing more frictional area is discussed on the project. We discussed about applying the frictional force on differential gear shaft also. To achieve this an inner shoe, which is less than the size of the outer shoe, is provided as per the design of the system developed with aid of UG modeling tool .This can be actuated by a specially designed cam which will actuate both outer shoe and inner shoe respectively. During braking the outer shoe will engage previously to absorb energy in the drum before the inner shoe get actuated. When the cam moves both the shoe remaining energy in both shoes shares the vehicles. This entire system is analyzed by using FEA tool and ANSYS to determine the stress developed in it .These results’ are compared with the braking system.
