Abstract:A 2-D axis-symmetrical thermo-mechanical coupled finite element model of vacuum hot bulge forming process of rotor can was established using non-linear finite element software MSC.Marc.The radius-direction displacement variation of rotor can and die were calculated and analyzed.The bulging dimension and internal diameter of rotor can after bulging forming were predicted.In addition,the effects of bulging clearance on the bulging dimension and internal diameter of rotor can after bulging forming were discussed on the basis of developed finite element model.The results indicate that,when the bulging clearance increases,the bulging dimension of rotor can decreases linearly and the internal diameter of rotor can after bulging forming never changes.The corresponding vacuum hot bulge forming experiments were conducted to verify the reliability of the finite element model.
