Abstract

Flexible plate spring plays an important role in gap seal and reliability of free piston Stirling heat pump. Eccentric flexible plate spring is widely used in Stirling machine because of its better stress distribution and larger radial stiffness ratio. In this paper, the influence factor of three-groove eccentric involute flexible plate spring eccentricity is analyzed in detail, and the value range of eccentricity in the design process of eccentric flexible spring is obtained by establishing a mathematical model. Through finite element analysis, the variation of radial and axial stiffness of eccentric flexible spring with different eccentricity is summarized. This study provides a basis for the design of later eccentric flexible spring.
