Abstract

Abstract

In order to improve the modeling precision of nonlinear components' mathematics models in vehicle dynamics simulation, the dynamics properties of one/two dimension columbic friction pairs, the friction wedge of three piece bogies and the damper with series stiffness were analyzed, their unconventional mathematics models were set up without velocity variable, their Simulink programs were designed, and their characters were compared with traditional models. Analysis result shows that the models overcome the numerical computation problems resulted from traditional models, have higher computational precision and efficiency, and their computational velocities increase by 2~10 times according to the scales of the models and the numbers of their nonlinear components. 24 figs, 10 refs.
