Statics Analysis of Integral Impeller Based on Finite Element

Abstract:

Aim at the problem of machining integral impeller, a method of using finite element theory to carry out the statics analysis of impeller in this paper is studied. The finite element model is established, and then the nephogram of the impeller stress, strain and total deformation are obtained. The result is attained: in the case of impeller rotation and statics load, the maximum of stress and strain occur at the root of suction surface, the maximum of total deformation occurs on the blade tip position of suction surface, while the maximum deformation position has not changed, which increases with the increasing of rotation and statics load. The data results provide a theoretical reference for the machining of integral impeller.
