Abstract : three - dimension wheel - rail contact geometry is taken into account in studying the vibration between bridge and vehicle . the iteration method of wheel - rail creep force is proposed to improve the existed calculating method 文摘:对车桥耦合振动研究中轮轨关系的线性方法进行了改进,提出考虑三维非线性轮轨接触几何,采用迭代法求解法向力和蠕滑系数。
