Design and Analysis of Brake Pedal.

Abstract

Brake pedals are widely used in all automotives, which acts as a linkage between occupant and brake mechanism. Existing design seems to be overdesigned as per requirement FEA will be used to apply cantilever load optistruct solver will be used to perform material removing process. The model of an existing brake pedal was generated using CATIA V5 solid modeling. Existing design will be tested using strain gauge technique at tensile loading using UTM machine. Comparative analysis will be done with FEA and Experimental units. Conclusion and future scope will be suggested. The Brake pedal is again a very crucial component of an ATV as it would control the overall braking of the vehicle. Proper braking is very crucial in rough terrains with all four wheels locking so that the stopping distance is minimum. Hence a brake pedal needs to be designed in such a way it provides the necessary leverage and creates enough pressure for the brake fluid to reach all four wheels. A brake is a mechanical component that constrains the motion by absorbing the energy from the motion of the vehicle. When the brake pedal of the hydraulic braking system is pushed against the master cylinder, a piston pushes the brake pad against the brake disc which reduces the speed of the vehicle or stops the vehicle completely. Hence the brake pedal should be able to push the piston in the master cylinder completely with a full-length stroke and thereby provide equal pressure to all wheels. Currently, automotive industry continues to strive for light weight vehicle for improving fuel efficiency and emission reduction. It is crucial to design vehicles with an optimum weight for a better performance of the car. In this field, which has boundaries with fixed standards and regulations, manufacturers continue to work on characteristics, structures and types of the material to develop new components, which have same safety specifications but cheaper and lighter than current products.
