摘　　要：柔性板弹簧对于自由活塞斯特林热泵的间隙密封及其可靠性具有重要作用。在三槽偏心型渐开线柔性板弹簧设计过程中,偏心量为一重要影响因素。通过建立数学模型,得到了偏心型柔性板弹簧设计过程中偏心量的取值范围;通过有限元软件分析,得到了不同偏心量下偏心型柔性板弹簧径向和轴向刚度的变化规律;针对不同偏心量下柔性板弹簧的轴向刚度进行了实验测试,将实验结果与有限元分析结果进行对比,实验值与有限元分析结果能够较好的吻合。该研究为之后偏心型柔性板弹簧的设计提供了参考依据。Flexible plate spring plays an important role in the gap seal and reliability of free piston Stirling heat pump.In the design process of three groove eccentric involute flexible plate spring,eccentricity is an important factor.By establishing the mathematical model,the value range of eccentricity in the design process of eccentricity flexible plate spring is obtained.Through finite element software analysis,the changing rules of radial and axial stiffness of eccentric flexible plate spring with different eccentricity are obtained.The axial stiffness of the flexible plate spring with different eccentricities was experimentally tested,and the experimental results were compared with the results of the finite element analysis.This study provides a reference for the design of eccentric flexible plate spring.
