Simulation of the Interaction between Vehicle Wheel and the Unevenness of Road Surface

Abstract

A model of the relationship between a vehicle wheel and the unevenness of the road surface is defined.The wheel is considered to be of circular shape. For a given form of unevenness, the excitation functions are evaluated for the individual subsystems of the dynamic vehicle model having 5 degrees of freedom. The vehicle model traverses the uneven surface at a variable velocity. The model provides for the study of the complex dynamic phenomena which occur between the wheel and the unevenness. The response of the model also includes the dynamic stress on the drive when the wheel passes over the unevenness of the road surface.

Sliding-mode observers for systems with unknown inputs: Application to estimating the road profile

“…Measurement of road roughness has been the subject Finding a way to obtain a three-dimensional proof numerous research studies for more than 70 years file from the dynamic response of an instrumented [2][3][4][5]. Methods developed can be classified in two car driven on a chosen road section is the general types: the response type and the profiling method.…”

Dynamic response and optimization for suspension systems with non-linear viscous damping

“…Suspension systems are important devices for reducing oscillations caused by the interaction of the vehicle with the unevenness of the road surface (see, for example, reference [1]). A suspension system, consisting of a frame, tyres, springs and viscous damping elements, is quite complex and highly non-linear.…”
