system modelling please help immediately
In the figure, the suspension system is composed of a damper and spring having the damping and stiffness coefficients of \(\mathrm{C}=60[\mathrm{Ns} / \mathrm{m}]\) and \(\mathrm{K}=7200[\mathrm{~N} / \mathrm{m}]\)respectively. The test rig shown in the figure is used to obtain the oscillation characteristics of the suspension system in the \(y\) -direction. The input of the system is given as the road profile as a sine function and it is given by velocity \(V\) in \(x\) -direction. The tire attached at point \(O\)...
