Effects of Various Road Conditions on Dynamic Behaviour of Heavy Road Vehicle

Abstract

AbstractThe studies on vehicle vibration to analyse dynamic behavior is one of most interesting topic of researchers in the field of vehicle dynamics. The main focus of this paper is to analyse the dynamic behavior of road truck at different road conditions. The road conditions are considered as on-road and off-road conditions. It has been noted that the designs of vehicle for on road and off road conditions are entirely different. On-road vehicle having a more clearance gap than off-road vehicle and size of tire is also large for off-road vehicle as compare to on-road vehicle. In this paper full car model is to be established to analyse the dynamic behavior. This model will be generated through the bond graph approach. Bond graph is a convenient full tool to incorporate multi-energy system in to a single frame of energy. This paper also highlights some recent modelling aspects in vehicle dynamics and suggests further development. Further, an integrated computational model of heavy road vehicle is created using various control strategies through bond graph technique to analyse its dynamic behavior. The simulation of this model reveals some interesting phenomenon on various road input conditions
