The issues about mechanical analysis are introduced in developing extravehicular pressure suit. Finite element modeling methods are discussed for the hard structure of extravehicular pressure suit. A finite element model has been established after a grading modeling concept for the solution of complicated structure modeling is proposed. Some results and their engineering applications are given for typical working states. The results calculated with the finite element model based on our method agree with those from test and provide reliable analyzing data for structural design and test for extravehicular pressure suit.
