摘　　要：板弹簧支承技术是线性压缩机的关键技术之一,在为活塞提供轴向回复力的同时,还用来支承压缩活塞、保证密封间隙。在优化分析的基础上,文中设计制造了一款三臂涡旋板弹簧。利用ANSYS有限元软件分析了该款板弹簧的轴向刚度、径向刚度、应力分布以及固有频率特性,并对板弹簧的轴向刚度和固有频率进行了实验研究。实验结果表明,采用有限元分析方法分析板弹簧性能是有效的。As one of the key technologies in linear compressor, flexure spring provides the compressor pistons with not only reciprocating force but also radial support for remaining the seal gap. Based on optimum analysis, a set of three - arm spiral flexure springs is designed and fabricated. Its axial stiffness, radial stiffness, stress distribution and natural frequency are analyzed using ANSYS software, and some experimental study about the axial stiffness and natural frequency is also carried out. Experimental results verify the validity of finite element analysis method in analyzing the performance of flexure spring.
