Analysis of Influence for Steering Performance of Vehicle on Road Surface Roughness

Abstract:

It is very important that the flexible tires have some effects on the movement of the vehicle. To analyze the influence of the flexible tire on different road surface roughness in the steering movement of the vehicle, the paper cites the traditional two degrees of freedom (2-DOF) model for steering movement of vehicle, analyzes deformation of the tires when the flexible tires scroll on the hard and soft road surface. The paper establishes mechanical model about the relationship of the tires and different road surface, and advances mathematics equation in the typical 2-DOF model. To verify theoretical derivation the tests of steering motion of the vehicle are done on the different road surface roughness.The results show that yaw rate of the vehicle is very different on the soft and hard road surface when the vehicle steers along the same turning radius path and at the same speed. The results illustrate that analysis of theory is right.
