Dynamic Simulation of a Prototype Race Car Driven by Series Wound DC Motor in Matlab-Simulink

In the last decade student teams at the Faculty of Engineering of the University of Debrecen have designed and constructed several race cars with alternative (electric or pneumatic) drives and took part and achieved successes in domestic and international competitions. For more successful racing a simulation program has been developed in Matlab for the calculation of the vehicle dynamic functions of the cars from their technical data. Currently, it has become a prerequisite of successful racing because of the large number of the possible values of technical data we can select the optimal ones by applying the above program combined with an optimizing procedure. The detailed description of the developed dynamic model and simulation program, together with the vehicle dynamics functions generated by the program are presented here. The description of the optimizing procedure will be presented elsewhere.
