摘要：To solve the strength problems of blade cascade of high-power hydraulic retarder used on special vehicles, a numerical simulation is calculated to get the pressure distribution under steady working condition based on 3-D flow field theory. And the finite element model of hydraulic retarder cascade is established. Based on the one-way fluid solid interaction theory and globally conservative interpolation algorithm, the fluid pressure load from flow field mesh nodes is successfully convert to structure mesh nodes. The centrifugal force is applied on the rotating rotor. Then the equivalent stress and the total deformation distribution are obtained. The results shows that the strength analysis model is accurately and reliable, and it is an effective method for the finite element analysis of blade wheels of hydraulic component.
