摘要: 斜圈弹簧在医疗器械、高压开关、汽车工业等领域应用广泛. 但其结构特殊, 受力复杂, 目前尚无有效的理论计算方法得出其载荷位移曲线, 只能通过数值仿真的方法研究其力学性能. 利用有限元软件ANSYS参数化建立环形斜圈弹簧有限元模型, 通过对模型的分析求解, 得出了其主要参数线径、节距、倾斜角与斜圈弹簧力学性能之间的关系. 研究了斜圈弹簧工作状态下的受力变形情况, 计算分析结果为斜圈弹簧的优化设计和合理应用提供了理论依据.

关键词: 斜圈弹簧|力学性能|有限元分析|载荷位移曲线

Abstract: The canted coil spring is widely used in the medical equipment, the high-voltage switch, the auto industry and other fields. Because of its special structure and complex stress state, there is no effective theoret-ical calculation method to obtain the load-displacement curves except for experimental and numerical methods. In this paper a finite element model of the canted coil spring is established on the ANSYS software platform to obtain its load-displacement curves. The relationships of the wire diameter, the pitch, the magnitude of inclina-tion of the canted coil spring with its load-displacement curve and the stiffness under a fixed load displacement condition are analyzed. The deformations of the canted coil spring under the working condition are studied. The calculation results provide a theoretical basis for the optimization design and the application of the canted coil spring.
