Topology Optimization Design and Modal Analysis Based on Header Frame of Combine Harvester

Combined with the working environment, a topology optimization design plan was applied to the header frame of a combine harvester. The dynamics of the optimized header frame were evaluated through modal analysis, and the final optimization plan was determined. The results showed that with little effect on the equivalent maximum stress and total deformation, the optimized header frame had reduced mass of 20.24%, achieved the goal of lightening.
