摘　　要：基于一种费马曲线的柔性弹簧,设计出不同略角、厚度、弹簧臂数和槽首尾封闭方式的多种柔性弹簧。利用ANSYS软件对多种几何参数的费马型线柔性弹簧进行了有限元分析,通过分析不同参数的费马型线柔性弹簧的最大应力值和径、轴向刚度的变化特性,总结了略角、厚度等结构参数对费马曲线柔性弹簧性能的影响规律;通过改变槽首尾端封闭方式实现了对略角为300°—360°的柔性弹簧性能的优化。Based on a spiral curve of Fermat flexure spring,many types of the flexure spring discs with different curve angle,thickness and spiral arm were designed.The characteristics of the Fermat flexure spring,including the maximum stress,radial and axial stiffness were analyzed by ANSYS software.The influence rules of structure parameter on performance of Fermat flexure spring were summarized,Fermat flexure spring performance of 300°-360°curve angle were optimized by changing the closing method of spiral slot.
