Abstract

Tire characteristics play a very important role in earthmoving machine dynamic analysis. For vibration analysis of the structure machine, the contact tire-road needs to be simulated. In this paper, the authors present a numerical method to solve the non-linear contact problem between a tire and the road. A non-linear contact model is used to determine the kinematical parameters and contact force of the tire is rolling on a rough road. The contact force is used to calculate the response of the tire.
