摘要
利用ANSYS有限元分析软件对外径为120 mm的板弹簧进行了应力和轴向刚度分析,得出了弹簧的厚度、涡旋角、涡旋槽个数以及涡旋槽宽度这些几何参数与其应力分布特性和轴向刚度性能的关系。首次提出了一个刚度应力比的概念,用刚度应力比值的大小来评价板弹簧性能的好坏,并将其作为板弹簧的设计依据。
Abstract：An analysis was carried out on the stress and axial stiffness of flexure springs with 120 mm diameter using the finite element analysis software. A relationship was obtained between the performance of flexure spring and its geometrical parameters including spring thickness, spiral angle, number of spiral slot width. A concept of stiffness-stress ratio was proposed as the evaluation criteria of the performance of flexure spring, which can serve as the foundation of spring design.
