After analysis of probability distribution law of traffic flow, this paper puts forward the Section Vehicle Dispatch Model that ADAPTS to microscopic traffic simulation based on Poisson distribution.

On the basis of an integrated model of C62 freight car, the problem of modeling for liquid transport with containers with dynamic software SIMPACK and contact modeling method.

For achieving the dynamic simulation of air ABS, four math models whole vehicle model, single wheel model, tire model and arrester model were built in thesis.
