摘　　要：采用UG软件虚拟设计了玉米收获机中立轴式甩刀茎秆切碎装置三维实体,并应用机械系统动力学分析软件ADAMS构建了三维运动仿真模型,实现了在ADAMS环境下甩刀运动仿真分析和甩刀切割玉米茎秆仿真分析。仿真结果表明,甩刀运动初期刀片运动不稳定,刀片数量变化对切碎装置运动状态无明显影响,随着刀片数量的增加,刀片对其旋转销轴的作用力和刀盘对其旋转轴的作用力都有减小的趋势,切割玉米茎秆时切割力大小真实可靠。The 3D model of vertical shaft spindle cutter of corn harvester has been established by UG software and the mechanical dynamic software ADAMS was used to establish the 3D kinematic simulation model of the vertical shaft spindle cutter. Kinematic simulation for spindle cutter and cutting off corn stalk was accomplished with it. The results demonstrated that the movement of blades in initial time is instability and the force of cut off corn stalk is true and credibility.
