| 摘 要： | 现有压缩机用板弹簧刚度小、使用数量多，因此设计了一种盘簧。采用有限元法（FEM）对比了盘簧和柔性板弹簧的刚度，并从8种不同臂形的盘簧中确定了3种性能较优的臂形；分析了弹簧组的9种布置方式，发现将盘簧放置在两等厚柔性板弹簧之间时支撑性能较好；采用响应面目标优化法对弹簧组间距进行优化，优化后的径向刚度增大了37.5%；对优化后的弹簧组刚度进行了实验测试，并将其与FEM结果进行了对比。

| Abstract: | The existing leaf springs for compressors, which were used in a large number, had low stiffness, so a discoid spring was designed. Stiffness performance of discoid springs and flexible leaf springs were compared by FEM(finit element melhod), and 3 arm shapes with better performance were chosen from 8 different arm shapes of discoid springs. 9 different layout modes of the spring group were analyzed and it is found that the discoid spring placed between two flexible leaf springs with equal thickness show better performance. Response surface objective optimization method was used to optimize the distance of the springs in spring groups. After optimization, the radial stiffness is increased as 37.5%. The stiffness of the optimized spring group were tested and compared with the FEM results. |
