Abstract:
Suspension system design is a challenging task for the automobile designers in view of multiple control parameters, complex objectives and stochastic disturbances. For vehicle, it is always challenging to maintain simultaneously a high standard of ride, handling and body attitude control under all driving conditions. The problems stem from the wide range of operating conditions created by varying road conditions, vehicle speeds, and loads. A good vehicle suspension system should have satisfactory road holding ability, while still providing comfort when riding over bumps and holes in the road. When the vehicle is experiencing any road disturbance such as pot holes, cracks, speed breaker and uneven pavement, the vehicle body should not have large oscillations, rather the oscillations should dissipate quickly. This research is carried out to study the performance of two basic suspension systems with a different approach, passive and active suspension system. For the simplicity, mathematical modeling is done by assuming 2 degree of freedom (2 DOF) system. Quarter car model is used to simplify the system. To analyze the model, simulation software MATLAB/SIMULINK is used. Results show that active suspension system has better ability to reduce the pick overshoot of sprung mass and also provides better damping quality than passive suspension system.
