Dynamic Modeling, Theory and Application Using Bond Graph

Abstract

The paper describes the technique for presenting quantitative and systematic modeling and simulation using Bond Graph for the vehicle dynamic system. It is based on the relative contribution of the new generation of a system equation, expression, result analysis and simulation through graphical display. The portioning algorithm can be employed to the existing automated modeling techniques for efficient, accurate simulation towards the design of the vehicle dynamic system. The design of control oriented four wheeled vehicle is widely recognized to be a very challenging task. This allows accounting for the driver turn angle which necessitates about visualizing the real driving behavior and its effects on the overall vehicle dynamic system. The study also illustrates an introduction to vehicle dynamics with emphasis towards the influence of its various properties. It also discusses the steady–state behavior of simple automobile models and transient motion when small and large steering inputs and other disturbances are employed. The effect of various shape factors and type of characteristics on vehicle handling properties is analysed. In order to design a controller, a good model representing the dynamic system is needed. From the input parameters considered, the results of the modeling and simulation of vehicle dynamics through the Bond Graph are found efficient and more accurate.
