The main goal of this paper is to study how non-linearities of components and subjective ride comfort perception quantity assessment influence the ride comfort, and find the best setup of vehicle carrying spring and damper parameters via optimization of a conceptual quarter-car model. In the paper is also a disscussion of how to create proper representative of the road exitation considering the properties of the stochastic road derived by power spectral density from time domain simulation. Comparison of the results from numerical integration and from frequency domain analysis and the influence of simulation time and time step on frequency bandwidth and accuracy of the results are also mentioned. Objective function for ride comfort optimization is in this paper defined as the sum of the normalized human perception quantity and the normalized normal tire force distribution.
