Abstract

Abaqus software are used to analyze the seeding wheel's stress distribution and displace-ment deformation during the working process , and the seeding wheel's stress distri-bution and displacement cloud maps are obtained. Topological optimization analysis was con-ducted on the seeding wheel to obtain the optimized finite element model. Based on the finite ele-ment model, the original 3D model was modified to obtain the topologically optimized 3D model of the seeding wheel. The results show that the optimized seeding wheel reduces its mass by 48.4%, achieving a lightweight design of the seeding wheel structure.
