| Abstract: | Vibration source and characteristics were analyzed in Stirling cryocooler,the natural frequency of cold finger were calculated using beam model.Designing methods on passive absorber was explained in theory.Based on the analysis,the dynamic absorber was selected as vibration controlling in pneumatically driven expander in split Stirling cyocooler.A dynamic absorber was designed based on the theory predicition.The experimental result shown it was fully agreement with theory prediction. |
