摘　　要：切割机构的刚度对甘蔗破头率有着显著的影响,因此要解决破头率高的问题,就必须令切割机构的设计满足高刚度的要求。通过分析基本原理,提出了一种增加切割支撑杆的新型高刚度切割装置的设计方法,并利用虚拟仿真和物理试验相结合的方法,分析比较了增加切割支撑杆及不同支撑间距对切割机构刚度和甘蔗断面切割质量的影响。结果表明,该新装置设计能令小型甘蔗联合收获机切割机构的刚度提高15.30%,甘蔗断面切割质量得到明显提高。When designing cutting device great effort should be laid on enhancing the cutting stiffness as the cutting stiffness has notable influence on the sugarcane cutting quality.Based on the cutting mechanism analysis,this paper proposes a new design of cutting device to increase the cutting stiffness by properly adding an auxiliary support bar and builds up 3D model for it.Then combining of virtual simulation and physical experiment,it compares and analyzes the different stiffness and cutting quality with support bar in various support position or without it.The result shows that such design can raise 15.30% of the cutting stiffness,and consequently improve the sugarcane cutting quality.
