采用不同材料的板簧垫片，簧片间摩擦系数亦有所不同，因此设计钢板弹簧时仅考虑钢与钢的接触摩擦将造成其性能分析结果的不准确。针对这一问题，利用 ANSYS 软件的接触非线性功能，对少片变截面钢板弹簧的等效应力及刚度特性进行分析，得到不同摩擦系数下的 VonMises 应力分布和载荷变形曲线，重点讨论了摩擦系数对钢板弹簧应力及刚度特性的影响；同时对钢板弹簧进行相应的性能试验。结果表明：少片变截面钢板弹簧的应力计算值和测试值误差较小，刚度仿真计算值和试验测量值基本吻合，相对误差小于5%，说明有限元分析能精确地模拟各簧片间的接触和摩擦问题，真实反映钢板弹簧的受力和变形情况，可用于研究簧片间不同摩擦系数对钢板弹簧应力及刚度特性的影响。

With different materials of gaskets,friction coefficient between reeds is also different,so performance analysis result is not accurate when contact friction between steels is only considered in the design process.The VonMises stress and stiffness characteristics of leaf spring were analyzed with the nonlinear contact function of ANSYS software,and the stress distribution and load-deformation curve were obtained.Meanwhile,the test of taper-leaf spring was performed.The results have shown that the differ-ence of stress between calculated and tested value is relatively small,and the calculated values of stiffness basically agree well with tested one,and the relative error is less than 5%.This indicates that finite ele-ment analysis(FEA)can accurately simulate the contact and friction and reflect the forces and deforma-tions,and can be used to discuss the influence of different coefficients of friction between spring leaves on the equivalent stress and the average stiffness of the taper-leaf spring.
