摘　　要：切割系统是甘蔗收割机的重要部件,直接关系到整机的工作性能。通过UG和ADAMS建立甘蔗收割机切割系统的虚拟模型,采用虚拟样机技术与正交试验设计相结合的方法对提高切割系统的输送能力进行虚拟试验。仿真结果表明,通过增加下压蔗辊、增加甘蔗与螺旋机构的摩擦系数以及在刀轴上增加橡胶元件可以提高甘蔗的输送速度。田间试验表明,采取上述措施提高了甘蔗的输送速度和收获质量,验证了虚拟仿真试验的正确性。该文为小型甘蔗收割机的机械设计提供了参考依据。Cutting system is the key component of sugarcane harvester and is directly related to the working pe^ormance of the machine. Virtual model of the cutting system was built in UG and ADAMS software. To improve the transmission capacity of cutting system, virtual experiment was carried out by using virtual prototype technology combined with orthogonal experiment design method. The simulation results showed that transmission speed was improved by equipping aggressive knockdown roller, increasing the friction coefficient between sugarcane and spiral mechanism and adding rubbers on the cutter shaft. Field test indicated that the transmission speed and cutting quality of sugarcane was modified significantly by taking above measure, and the correctness of virtual simulation experiment was＇verified. It can provide reference for the mechanical design of the small whole-stalk sugarcane harvester.
