The modeling methods about vestibule diaphragm, coupler and draft gear are introduced, too. Among the six Models, Model A and Model B can be used to study the vehicle stability and curve negotiation under different track situations. Model C and Model D can be used to carry out the stability, dynamic curving behavior and ride comfort of the high-speed passenger car. Model E and Model F are three-dimension train dynamic models which consist of three cars (head car, intermediate car and tail car).
