| Abstract: | This paper mainly deals with the development of the nonlinear dynamic model for the speed-up freight truck in railway.In this paper a new two-dimension stick-slip friction model was developed and used in the freight truck model.On the basis of this model,we build many nonlinear component models,including bearing panel of the axle box,side bearing and pivot.Conseuently a new nonlinear freight truck was developed on those component simulation models.Meanwhile a linear dynamic model for the freight truck was built and compared with the nonlinear model. |
