摘　　要：剥叶断尾机构是小型整秆式收割机的重要部件,并且目前糖厂对于含杂率有一定的要求,因此其剥叶断尾效果将直接影响糖厂制糖效率。为了设计出行之有效的剥叶断尾机构,通过Solid Works和ADAMS建立甘蔗收割机的剥叶断尾机构的虚拟模型,采用虚拟样机技术对影响剥叶断尾效果的主要因素进行了仿真试验研究。结果表明,随着剥叶辊转速的提高和剥叶辊与甘蔗的交错深度增大,相应的打击力与摩擦力增大,但是过大的打击力会伤甘蔗,因此选取了剥叶辊转速900r/min和交错深度30mm为较优参数。该文为收割机的机械设计提供了参考依据。Cleaning leaves and breaking tails mechanism is the key component of small whole-stalk sugarcane harvester and the sugar-refinery has certain requirements for trash content, so the effect of stripping leaves tails is directly affect the efficiency of the sugar-refinery to refine sugar. Virtual model of the cleaning leaves and breaking tails mechanism was built in Solidworks and ADAMS software and virtual experiment was carried out by using virtual prototype technology to design an effective cleaning leaves and breaking tails mechanism The simulation results showed that with the increase of the rotating speed of the cleaning roller and the interleaving depth of the cleaning roller and sugarcane, the strike force and friction as the same. But excessive force would hurt sugarcane, so the rotating speed of the cleaning roller of 900r/min and the interaction depth of the cleaning element of 30mm is the optimum parameters. It can provide reference for the mechanical design of the small whole-stalk sugarcane harvester.
