Vehicle suspensions are one of the most important equipment in an automobile which impart comfortable ride to the passengers. As the passive suspensions are most widely used in the automobiles, therefore this paper deals with the investigations of the suspension behavior at the different values of the road profile amplitude. The effects on the frequency plots are studied by using fast Fourier transform functions. The phase plots are also drawn to understand the periodic and quasi periodic transformations at the different values of road profile amplitude. It is seen that the natural frequency and its harmonics in the spectrum dies out with the rise in the values of the road profile amplitude and also the increase in the strength of forcing is observed. The in harmonics obtained is seen to be withdrawn with the increase in the road profile amplitude.
