Abstract：Objective The method of finite element analysis was used to provide effective data basis for the selection of the fixing state of the EVA spacesuit vibration test. Methods The finite element model of EVA spacesuit was established. The correctness of the model was verified through modal analysis and experimental data comparison, and then the response analysis under sine vibration was carried out to get the response of under two different fixtures. Results According to the response analysis under two different fixing states, it could be concluded that the simulation fixture was much closer to the real installation condition, and the spacesuit with the simulated fixture was more suitable for the sine vibration test. Conclusion The finite element analysis method could provide reliable analysis data for product test. For the complex structure, in order to avoid over test, it would better to use the simulation real fixing state to do the sine vibration test.
