Development of Accelerated Testing Technique for Evaluation of Brakes for Two and Three Wheelers

Brake system is one of the most important safety related sub systems for any automobile. This requires all auto majors to put more effort in design optimization of brake system and exhaustive evaluation for the same.

On-road evaluation of brakes is time consuming process and has other shortfalls like unsafe riding conditions, less repeatability, limitation of brake input force, speed, less control in test conditions, requirement of special track etc. Normal lab testing for brake system has several drawbacks like imprecise inertia simulation, more testing time, uncontrolled test environment, partial system level evaluation, huge rotating mass which may lead to unsafe operating conditions, frequent maintenance, etc. This paper describes about the methodology adopted, efforts involved and results obtained by developing an accelerated evaluation system for brakes as a complete sub system in laboratory.
