橡胶金属牵引组件纵向刚度的试验设计与研究

Experimental Design and Research of Longitudinal Stiffness of Rubber Metal Traction Components

设计一种橡胶金属牵引组件纵向刚度的新型试验方案,研究不同测量方式和加载方式对刚度测试结果的影响。结果表明:单边加载方式测量的刚度大于正反加载方式,打表测试的刚度大于系统测试;试验方案设计合理,满足试验要求,且能准确反映牵引组件纵向刚度,对牵引组件及同类产品的研发和试验有一定指导作用。

A new test program for the longitudinal stiffness of rubber metal traction components was designed,and the effect of different measurement methods and loading methods on the stiffness test results was studied.The results showed that the stiffness measured by single side loading was higher than that measured by positive and negative loading,and the stiffness measured by dial gauge was higher than that measured by system testing.The design of test program was reasonable,met the test requirements,and accurate longitudinal stiffness of traction components could be obtained,which could guide the development and test of traction components and similar products.
