摘　　要：采用UG软件虚拟设计了玉米收获机中立轴式甩刀三维实体,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,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 not stable and the force of cutting off corn stalk is true and reliable.
