摘　　要：为设计适用于斯特林制冷机低温罩中超导滤波器的支撑结构,研究了模态分析方法和支撑设计中需要考虑的问题。通过对支撑结构进行模态分析,提出了适用于超导滤波器的支撑结构,并完成了整个制冷机及其低温罩内结构的加固设计。有限元分析和试验验证的结果表明,所设计的支撑结构具有固有频率高,质量轻等优点,能够满足试验条件,并可以作为其他支撑结构设计的参考。In order to design a support structure that suits superconducting filter in cryogenic vessel of stirling cooler,the method of modal analysis and the principles of designing support structural are studied.The nature frequency and the vibration modes of different types support structure are analyzed.Then,a structure that support superconducting filter is proposed,and the reinforced design of structure for the cooler and the cryogenic vessel is done.The analysis and experiment results indicate that the structure has a high resonance frequency and a light mass.It can meet all the test conditions and be a good reference to the design of other support structure.
