The models which can be treated are: multibody rigid or elastic vehicles, any degrees of freedom, kinematic constraints; a variety of linear and nonlinear suspension laws including active control systems; elastic guideways (or bridges) including irregularities; the nominal track can be straight and level but also curves, grades as well as variable velocity can be simulated. Special features of the resulting simulation program are: automatic generation of the linearized system equations, generation of subroutines by the program to reduce the numerical effort, modular construction of the whole program. The time-response of the overall time-varying and possibly nonlinear state-equations is obtained via numerical integration. The program is supplemented by evaluation and interpretation routines which allow one to compute vehicle stability, controllability and observability as well as the transfer function matrix. Also, the time-responses can be Fourier-transformed and vehicle ride-quality can be calculated. As a typical application, the simulation of a design of an electrodynamic repulsion system is presented for both the magnetically suspended- as well as the emergency-mode.
