柔性板簧对于太阳能斯特林发电机的间隙密封和活塞的轴向定位起到了决定性的作用。在总结了国内外柔性弹簧研究的基础上，针对同心涡旋型柔性弹簧，利用WB( workbench)对板簧参数化模型进行了有限元分析，比较了板簧截面各参数对板簧最大应力和固有频率的影响。以板簧的行程为限制和板簧的最大应力为设计目标，对柔性弹簧进行尺寸优化。%Flexure spring plays an important role for the clearance sealing and axial location in the solar energy Stirling engine. Based on the flexure spring research, the concentric and involute flexure spring is chosen . The finite element analysis of its parameterized model is done by Workbench software, including the influence of flexure spring section parameters on maximum stress and natural frequency. The travel restrictions and the maximum stress are taken as design goal to optimize the sizes of the flexure spring.
