Optimization of working parameters for sugarcane cutter

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.
