Coupled disturbance analysis of a pulse tube cryocooler

摘要：

　　To predict accurate micro-vibration produced by a spacebome payload mounted pulse tube cryocooler (PTC), a coupled disturbance analysis of cryocooler with flexible support structures have been discussed and investigated.A coupled transfer function matrix is introduced by improving the traditional disturbance analysis.According to the coupling disturbance relationship between the source and supporting structure, microvibration input load is accurately obtained.Based on the finite element model of the space camera, the performance of optical system is analyzed.Compared to the decoupled method, this coupled method can accurately predict the local transfer characteristics between cryocooler and interface.
