| Abstract: | The trial-manufacture process of the thick-wall cylinder simulation tubes made by 38CrNi3MoV steel was introduced,and simulation experiments of the hydraulic autofrettage and static intensity of the six thick-wall cylinder simulation tubes were done.The experiment results indicated that in the condition of the wall thick ratio 1.6 and 1.65,autofrettage pressure 720-780 MPa and the material intensity Rr0.1≥1 280 MPa,the measured static intensity of the six thick-wall cylinder simulation tubes reaches 520-575 MPa after hydraulic autofrettage,which is 70%-76% of the theoretic static intensity. |
