为分析弹性钢轨扣件轨道的轮轨作用力，通过建立地铁车辆弹性扣件动力分析模型，分析了扣件刚度、列车运行速度等对轮轨作用力的影响。

This paper sets up a dynamic analysis model of subway vehicle-elastic fastener and analyzes the influence of fastener stiffness, train operation speed on the wheel-track force.

为此，扣件必须具有足够的强度，耐久性，和一定的弹性，并有效第保持钢轨与轨枕之间的可靠联结。

Therefore, buckles to have the enough intensity, the durability, with certain elasticity, and effective maintains between the rail and the railroad tie reliable joint.
