Abstract

This document discusses computing time reduction possibilities for the dynamic simulation of large nonsmooth multibody systems. Exemplary regarding the model of a pushbelt continuously variable transmission known from literature, simplifications are derived to examine the underlying problems. Usually one has to deal with the calculation of an adequate initial state and the reduction of the computational effort during integration. In three sections stationary belt models for the determination of an initial value are proposed, time step size enlargements due to implicit time integration schemes are analysed and the distribution of themain effort per time step on several central processing units by shared memory parallelisation is investigated.
