Research And Application Of Object-Oriented Vehicle Dynamics System Modeling

With the development of computer simulation Object-Oriented Modeling theory and software Engineering, these techniq es have gained their widely use in solving problems faced with traffic and trining. Simulation techniques give us a powerful supporting on research in vehicle dynamics simulation.In vehicle dynamics study before, we always take one model or process as our research object. And, when developing simulation program, the whole program like a water fall pouring down, makes the program difficulty to maintain. So. in this article, we try to using Object-Oriented Modeling and Programming method .Firstly, according to Object-Oriented Modeling theory, we disintegrated the whole vehicle into seven parts: Engine, Driving system. Braking system. Steering system, wheel. Suspension and Vehicle body. Then analysis the attributes and operations of each part. Based on this . each part's mathematical model is constructed. The whole vehicle model has eight degrees of freedom. Finally, On Windows Operating system, Using Microsoft Visual C-H-6.0, realized the vehicle modeling program.This program can be used to compare and verify models, and integrate to a whole according to your selections. It can simulate vehicle's running condition. To a certain extent, it has it's practicability.
