The initial model consists of a quarter vehicle with the following parameters:
cW = 150,000 N/m; cB = 21,000 N/m; kW = 100 Ns/m; kB = 1500 Ns/m; mW = 40 kg; mB = 400 kg
The figure shows the effects of the road signal on the vertical displacements, velocities and accelerations of the wheel and body. Damping and reduction of the motion parameters between road and body can be clearly seen. For better understanding, the curves for body and wheel have been vertically displaced.
