Simulation of a vehicle passage through an individual road irregularity

Abstract

Investigation of mechanical vibration of a vehicle is still current topic. This phenomenon effects dynamic properties of the vehicle. Mechanical vibration of vehicles during running are caused mainly due to road irregularities. Vibrations are signified as deflections of individual parts of a vehicles. Depending on deflection magnitude, they can be perceived only as slight oscillations or, in case of rough terrain and higher running speed as significant shocks leading to adverse passenger comfort, decreased driving safety and extraordinary loading of a road. The article presents a simplified way to analyse the vehicle running through a road irregularity using mathematical approach as well as results of dynamic analysis of a vehicle computational model for running through a road irregularity.
