The purpose of computer modeling of a vehicle system is to develop basic methods for computer formulation and solution of the equations of motion. This requires systematic techniques for formulating the equations and numerical methods for solving them. The computer program developed here for the analysis of vehicle system dynamics is a special purpose program. It deals with only a specific type of application say lateral stability or dynamic response. The equations of motion for that particular application are derived a priori and then formulated into the program. As input to the program, the various data's like, mass of the entire vehicle, sprung mass, unstrung mass etc., the initial values of parameters of a vehicle system have been provided. Such a special purpose program can be made computationally efficient and its storage requirement can be minimized with the result that it will be suitable for implementation on small personal computers.Keywords

In India Automobiles provide a vital infrastructure for the growth of industry and agriculture. Human civilization has inevitably relied on substantial movement of passengers and goods in a speedy manner and the volume of this has gone up enormously with massive rise in population and economic activity. The demand of higher operating speeds, greater axle loads, better riding comfort and more running safety has attracted the attention of professional talents to give a serious thought to the problem of vehicle system dynamics and to devise ways and means to achieve the above requirements through effective methods. At present, the researchers are trying to develop mathematical and computer models, which not only provide a more exact simulation but enable studies to be carried out on stability or response, comfort and optimization of the design characteristics of various components of the vehicle system. Vehicle dynamics, stability deals with the study of vehicle in motion under the action of various forces. Any vehicle comprises of linear as well as angular movements along and about the three mutually perpendicular coordinate directions x, y, z. The linear movements are longitudinal, lateral and vertical displacements and the angular movements are rolling, pitching and yawing respectively for x, y, z directions.Keywords
