A finite element analysis of blade wheel strength of a high-powered torque converter's

To solve the strength problem of blade wheel of a high-power torque converter used on tracked vehicle, a analysis model is set up for the blade wheel strength of torque converter based on the one-way fluid solid interaction (FSI) theory. A globally conservative interpolation algorithm is used to convert the fluid pressure load from flow field mesh nodes to structure mesh nodes. In the light of inertial centrifugal load, the statics method is used for a finite element strength analysis of a blade wheel of torque converter under the two loads, and its stress distribution and deformation state are obtained. Two hazardous working conditions-the starting working condition and the maximum power working condition-are analyzed in detail. An effective method is provided for the strength analysis of blade wheel.
