Abstract

This paper addresses some of the deficiencies and limitations of current methods used for synthesising random vehicle vibrations. When wheeled vehicles traverse irregular surfaces, the interaction between the vehicle and the terrain give rise to a dynamic process that produces complex forces and motions within the vehicle. Because pavement surface irregularities are generally random in nature, the resulting vehicle vibrations are also random. Furthermore, the levels of the resulting vibrations are not solely dependent on the pavement roughness but are also a function of vehicle type, payload and vehicle speed. The effect of these parameters tends to make the complex mechanical interactions between the vehicle and pavement surface difficult to characterise and predict. It is therefore widely acknowledged that the analysis and simulation of road-related vehicle vibrations demand some level of sophistication.
