Abstract

The vibrational response of a quarter car model simulating a car moving over regularly spaced road bumps is presented. To achieve this goal, the quarter car model is described and profile of the sequence of road bumps is modelled. The analytical evaluation of the obtained dynamic equations provides knowledge on the relationship between the different physical parameters to avoid high amplitudes of vibration of the sprung mass. Additionally, we have obtained the amplitude equation of the sprung mass for the quarter car crossing the bump which is crucial for possible predictions on the sprung mass amplitude. Numerical analysis leads us to conclude that the length of the bump and their spacing along the road are crucial to avoid high amplitude of vibration for the sprung mass. Thus, it is shown that the comfort of passengers inside a car moving on a road with evenly spaced bumps will be ensured if the physical parameters of the suspensions are well chosen by the engineers.
