Research on Lightweighting of Header Frame Based on Multi-objective Genetic Algorithm of MOGA

In order to accelerate development requirements of high-end agricultural machinery and equipment in China and achieve development goal of “green and low-carbon”, this project is based on header Frame of a combine harvester. Based on finite element analysis, the main components of header Frame are optimized using multi-objective genetic algorithm (MOGA) with optimization objectives of minimizing mass and increasing first-order modal frequency. Finally, optimization solution is obtained.
