| Abstract: | In order to verify the reasonability of structure design and material selection of high-pressure gear pump body, based on ANSYS Workbench software, the structural static mechanics and thermodynamics of gear pump body are analyzed comprehensively. Then the total deformation and equivalent stress distribution of the pump body under the working state oil pressure and temperature are obtained. The results show that large deformation occurs near the high pressure outlet of the pump body and the maximum equivalent stress occurs in the inner wall of the outlet hole. In order to reduce the deformation of the pump body, the structural is optimized, and the feasibility of the structural optimization is proved by simulation. |
