| 摘 要： | 为减小弹簧组件体积并满足制冷线性压缩机的刚度需求，设计出一种基于阿基米德螺线的圆柱臂盘簧。采用有限元分析方法对涡旋臂板弹簧和新型圆柱臂盘簧的径向与轴向的刚度变化、应力变化特性和等效质量进行了分析对比，对两种弹簧的轴向刚度特性进行了实验验证，并将新型圆柱臂盘簧用于弹簧组件。研究结果表明，圆柱臂盘簧具有较大的径向刚度和轴向刚度，且动态刚度恒定，改进后的弹簧组在提供较大轴向刚度的同时有效减小了弹簧组的体积和质量。

| Abstract: | To reduce volume of spring assembly and meet stiffness requirements of refrigeration linear compressor, a cylindrical arm coil spring was designed based on spiral of Archimedes. Variation of radial and axial stiffness, stress characteristics, and equivalent mass of scroll arm plate spring, and a new type cylindrical arm coil spring were analyzed and compared by finite element analysis method. Axial stiffness characteristics of both type springs were verified experimentally, and the new type of cylindrical arm coil spring was applied to spring assembly. Research results show that the cylindrical arm coil spring has large radial stiffness, axial stiffness, and constant dynamic stiffness. The improved spring assembly provides greater axial stiffness and reduces volume and mass of spring assembly effectively. |
