ABSTRACT
Analyzing the index of the vertical stability and the curve negotiation of container flat wagon with different stiffness, the results show that the vertical bending stiffness of car body has influence on the vertical stability index, embodied in that the vertical bending stiffness increases, the stability is better, and has no effect on curve negotiation performance, and that the torsion stiffness of car body has great influence on the curve negotiation index, embodied in that the torsion stiffness increases, the curve negotiation safety gets worse.
