The dynamics phenomena of half railway carriage model with 17 degrees of freedom are investigated. The model is set to run on a straight track with the speed range between 85 and 165m/s. Shen-Hedrick-Elkins theory is used to describe the nonlinear relation between the creepage and the creep forces. A new method of flange contact as multi-body collision is also presented. Bifurcation diagram and the critical speed for jumping rail are obtained and further validated by the simulation. Finally, the phase plots of the flange contact are discussed.
