摘要
轨距扩大和钢轨侧翻将影响到轮轨接触点位置和动力作用。钢轨垫层和道床的刚度、钢轨刚度和扣件扣压力是影响轮轨之间作用力和轨距扩大的主要因素。
The widening of gauge and the overturning of rail will effect the contact point and dynamic forces between wheel and rail. The elastic rigidity of rail pad and ballast, stiffness of rail, and clamping force of fastener are the main factors that cause the widening of gauge. In this paper, the gauge widening and rail overturning under the different parameters of track structure are discussed.
