摘　　要：利用二次回归正交旋转设计的方法,建立了不同工况下甘蔗收割机切割器的工作参数:切割速度、前进速度、刀片数量、刀盘倾角、刀片刃角和切割角对工作性能指标破头率影响的二次回归方程,在此方程的基础上,考虑切割器工作参数对破头率的影响,建立了参数优化数学模型,采用约束变尺度法,实现了切割器工作参数的优化,降低了破头率,最后通过实验进行了验证.The quadratic regression equations of broken rate affected by the cutter＇s working parameters, including rotate speed of cutter, harvester forward speed, knife number, cutter obliquity,cutting angle and knife-edge angle,are established using the method of quadratic regression orthogonal rotatable design. Based on the equations,the effect on the broken rate of working parameters of sugarcane cutter considered, and the parameter optimal mathematical model is established. Then the working parameters of sugarcane cutter are optimized using the constrained variable metric method. The broken rate of sugarcane is reduced. The optimization result is proved by experiment in the end.
