چکیده
Vehicle dynamic analysis has been a hot research topic due to its important role in ride comfort, vehicle safety and overall vehicle performance.. For proper designing of suspension system, nonlinearities in suspension parameters must be considered. In this paper, nonlinearities of spring and damper are considered while preparing quarter car model. For this a simplified model and experimental set up for the same is developed. The deterministic impulses due to road profile are given by harmonic shaker which gives input motion to shock absorber. The sprung mass acceleration response obtained by FFT analyzer at sprung mass of quarter car model is compared with the results obtained by linear and nonlinear MATLAB Simulink models.
