AUTOMATED SYSTEMS USED FOR RAPID AND FLEXIBLE GENERATION OF VEHICLE SIMULATION MODELS EXEMPLIFIED BY A VERIFIED PASSENGER CAR AND A MOTORCYCLE MODEL

The present article deals with questions of a flexible and time saving generation of vehicle system simulation models covering a large range of model dimensions and operational requirements. For essential assistance two of the Newton-Euler formalism based methods for a computer assisted generation of the nonlinear or linearized equations of motion of mechanical multibody systems will be investigated with respect to user specific qualifications and handling features. The proceeding will be explained by the example of a verified complex passenger car model and in conformity with the requirements of a somewhat simpler designed motorcycle model. It can be shown that for the predominant amount of questions the linearized partly numerical and symbolic equations of motion will act satisfactorily. The time gained will be important. Including the generation of the vehicle specific trunk-model, the initial stage of model-building only takes 1/3 to 1/2 of the usual time. Structural modifications or future model expansion can be done within a few days; likewise, conversions to other vehicle systems can be done within a few hours. Restrictions with respect to realizable complex model structures, at this time, merely appear when using an absolute symbolical acting generation method.
