摘　　要：以重载扣件弹性垫板为例,通过对其静刚度和疲劳性能进行试验,分析了影响静刚度的主要参数。结果表明,打表位置、加载头面积和紧固扭矩是影响弹性垫板静刚度性能的关键因素,紧固扭矩对弹性垫板的节点刚度和疲劳性能的影响较大。With the pads of the heavy haul fastening systems as an example, the key factors to affect the main performance parameters of the pads were analyzed through stiffness tests and fatigue performance tests. The results showed that the main influencing factors on stiffness of the pads were the test position,the area of loading and tightening torque, but the effect of tightening torque on fas- tening assemble stiffness and fatigue property was significent.

关 键 词：重载扣件 静刚度 疲劳试验 紧固扭矩
