Abstract

This paper describes the vibration analysis using multibody vehicle model with a method for calculating the road input from the three-dimensional road model. The three-dimensional road model which produced the frequency characteistic of a road was made with the filtered Poisson process. The contact pressure and contact area affect the road input, for the distribution of the contact pressure and contact area are used as calculation factors in the proposed method. By using the method, the shape of the three-dimensional road were considered and the vehicle vibration could be analyzed.
