Abstract:
The ride comfort and safety is largely determined by the tuning of the vehicle suspension dampers. A methodology is developed to identify the influence of road excitation and of the top mounts on the optimal damper setting. Therefore this paper deals with a simulation routine, which minimizes the development effort of body damping systems on automobiles by using an analytical computation method. For this, a partly linear model is examined and evaluated in order to optimize its properties regarding ride comfort and road holding using an extended quarter-car model and a Pareto-chart. The influence of the road excitation level, the top mount and engine mount stiffness on the optimum damper characteristic is shown. This provides the starting point and the range for the tuning sessions during the vehicle development process.
