【Abstract】 It is hard to satisfy the engineering needs by using simplify methods to analyze centrifugal impeller.In order to find intensity and rigidity information of impeller detailedly, 3D modeling,analysis and design optimization is needed. A 3-D parametrization design project was developed to model impeller, aided by ANSYS.Based on this, a uniform assembly optimization design model including intensity and rigidity restrictions was advanced by analyzing three type of assembly technics of impeller(hydraulic pressure assembly, gear multiplying assembly, pull shank assembly).For different assembly impeller, an ideal optimization result can be gained as long as the optimization object was amended.In the end, an engineering example was presented in which a hydraulic pressure assembly impeller was optimized.It shows that this optimization method is reliable and efficient.更多还原
