【 摘 要 】

Stirling cryocooler becomes the research focus in many countries, because of high efficiency and compact structure. But the structure design, material selection and mechanical performance of spiral flexure spring, which is the key component of stirling cryocooler, is always an important problem. By means of in-depth study of spiral flexure spring of stirling cryocooler, the force model is established by finite element method. It is necessary to study its strength characteristics and analyze the influence factors. The simulation results are compared with the experimental results, which show that the method of the research, which the paper adopts, is feasible and effective. It also provides theoretical and engineering basis for design and analysis of spiral flexure spring of stirling cryocooler.
