Abstract: In order to improve the pressure bearing capacity of thick wall cylinder pressure vessel, the feasibility of autofrettage technology to improve the pressure bearing capacity of thick wall pressure vessel was analyzed by finite element software ANASYS, pressure bearing capacity of original thick wall cylinder and self enhancement treatments thick wall cylinder was comparative analyzed. The results show that: self enhancement technology has a significant effect on improving the bearing capacity of the thick wall cylindrical vessel, and it plays a guiding role in the design process of a thick wall cylinder pressure vessel.
