Abstract


This study is focused on isolation of passenger from tremors occurring due to road irregularities. A half-car model is considered to study the pitch acceleration of the body and the dynamic characteristics of front and rear wheels. This study includes an optimal control that ensures the pre-eminent suspension performance by limiting the active generated by the actuators should be within the limit and it is applied between vehicle body and wheel. The effectiveness of the system is examined through simulation with two road disturbance models which were designed to simulate actual road conditions with road irregularity.
The influences of the vehicles parameters on the vehicles dynamic characteristic and response are investigated. The results show that the proposed system provides improvement in ride quality while maintaining vehicle maneuverability.
