【Abstract】 A quasi-equal strength criterion for the design of discontinuous zone of pressure vessels was suggested in the sense of design by analysis. Taking the integral reinforcement of nozzle of high pressure spherical shell as an example, optimization mathematical model was established based on the quasi-equal strength design criterion. With the aid of APDL(ANSYS parametric design language) and OPT(optimization tools) of ANSYS, the structure optimization was done, and the optimization of discontinuous zone of pressure vessels in the sense of design by analysis was realized.更多还原
