摘　　要：针对蔗梢在榨糖过程中会降低甘蔗的出糖率,以及蔗梢部分进入甘蔗收割机物流系统不利于物流系统的正常运转、堵塞物流通道等问题,在原有物理样机上加装切梢装置。通过对切梢装置运动要求的分析,设计了切梢装置的液压传动系统,并用AMESim软件对系统进行了建模仿真分析;同时,试验分析了切梢装置马达的动态特性,并得到马达在不同状态下的动态特性变化,验证了方案的可行性;最后,通过田间试验测试了切梢装置液压系统流量及压力的变化,并获得了其在田间实际工作时消耗的功率。Cane top will reduce the rate of sugar in the process of sugar refining, and cane top part in the logistics system of sugarcane harvester is not conducive to the normal operation of the logistics system, for these problems, assemble a cane top cutting device on the original physical prototype. By analyzing the motion requirement of the top cutting device, design the the hydraulic transmission system, and use AMEsim software to simulate the system. Test and analysis the dy- namic characteristics of the motor of the top cutting device and get the changes of the dynamic characteristics of the motor under different work conditions, and the feasibility of the scheme is verified. At last, the flow and pressure of the hydrau- lic system of the cutting device are tested by field experiments, and obtain the power consumption of the system is.
