FEM Analysis and Structural Parameter Selection of Elastic Rings

摘要: 针对某轴系的弹性环式柔性支撑径向等效刚度分析问题,利用Ansys参数化语言APDL建立了考虑弹性环与内外支撑接触因素的非线性有限元模型,分析了弹性环环段数目、凸台弧度、弹性环厚度等参数对等效刚度的影响规律,并得到了等效刚度的分布规律。根据使用要求,综合考虑加工、安装、稳定性等因素,对其进行了详细的参数选择,提出了4种优选的结构参考方案。
- 弹性环 /
- 柔性支撑 /
- 有限元 /
- 等效刚度 /
- 结构参数选择
Abstract: To analyze the radial equivalent stiffness of the elastic-ring flexible support,the Ansys APDL language was used to establish the FEM model,which considers the nonlinear contact between the ring and the supports.The effect of variation of the ring's structural parameters,including the number of the segments,the circumference width of the boss,and the effective thickness of the ring,on the radial equivalent stiffness of the ring was analyzed by using FEM method and its variety laws were obtained.By taking into account the machining,assembly and stability requirement,the optimization analysis was carried out and four referenced structural schemes were provided.

- flexible support /
- finite element method /
- stiffness /
