Development of the ASIMO program, a general simulation program for vehicles, is reported, in particular the preparation of a dynamic vehicle simulation model based on the equations of motion. Three types of model are distinguished, corresponding to vehicles with static suspension, with primary and secondary suspension, and with an elastic track. Results are presented for an electromagnetic suspension vehicle test model. These show that the 46 eigenvalues of this vehicle can be typically grouped and interpreted. Track durations are determined by vehicular mass forces and only a little by the variable part of the magnetic forces. Meaningful numerical results may be expected for only carefully selected integration methods, notably those using constant steps.
