DYNAMIC CALCULATION OF RAIL VEHICLES: A CONCEPT FOR THE APPLICATION OF THE PROCESS OF STATISTICAL LINEARIZATION IN THE MANY BODY PROGRAM SYSTEM MEDYNA

LAUFDYNAMISCHE BERECHNUNG VON SCHIENENFAHREZEUGEN: EIN KONZEPT ZUM EINBAU DES VERFAHRENS DER STATISTISCHEN LINEARISIERUNG IN DAS MKS-PROGRAMMSYSTEM MEDYNA

A substructure for the wheel sets is developed. The problem of relating the substructures to the general body system by the calculation of statistical linearized, generalized force vectors for various linear and nonlinear joining elements is solved. Nonlinear spring and damper connections, Coulomb translation friction dampers, and Coulomb rotation friction dampers are covered. Statistically linearized dynamic connecting elements are modelized. It is shown how the general differential equation system is to be constructed. The iteration process for the determination of the free linearization parameter is presented.
