| Abstract: | Diaphragm spring in linear-driven Stirling cooler was analyzed by finite element method.The visible deformation graphics were presented for several cases of loads,and compared with the experimental data,then the validity of the finite element program was verified qualitatively.Through the analysis on the stress concentration and natural frequency,a new spiral flexure spring was developed in order to fit for the space use. |
