| Abstract: | The three-dimensional model of grain thresher is established by using SolidWorks software. The static analysis of the frame is carried out by ANSYS Workbench, and the stress distribution and deformation displacement of the whole computer frame are studied. According to the results of statics analysis, in order to reduce the mass of the frame, the topological optimization design of its structure is carried out. The results show that the mass of the improved frame is reduced by 10. 98% on the basis of meeting the structural usability and material mechanical properties, and the lightweight design of the thresher frame is realized and the manufacturing cost is saved. |
