Convergence Analysis of Dynamic Response of Double-Drum Vibratory Roller under Random Road Excitation

Abstract

The main role of the vehicle suspension system is to achieve driving stability and passenger comfort regardless of the road surface. Usually, we solve the optimization problem for road surfaces with either regular or random undulations. This paper will consider the convergence property of the dynamic response of the system when considering the road surface as random excitation. The goal is that we will find the number of calculation cases corresponding to the dynamic parameters of interest to obtain the objective function value in the optimization process. The contribution of the present paper is shown with the calculation case of a double-drum vibratory roller.
