摘　　要：将有限元法和遗传算法相结合对某农用车车架进行了结构优化。优化模型以车架总重量最小为优化目标,以各主要梁的位置和尺寸为设计变量,以车架刚强度为约束条件进行优化。优化后模型减重7.6%,取得了较好的优化效果。Structural Optimization of agricultural vehicle frame was realized by organically combining finite element method with genetic algorithm. The optimized model used minimum frame mass as optimization object,the locations and dimensions of some beams as design variable,stiffness and intensity as constraint condition to optimize. The weight of the frame was decreased 7.6% after optimization. The effect was good.
