摘　　要：为提高灭茬刀辊设计的可靠性和效率,基于UG-NX3软件,根据运动方程绘制刀刃运动轨迹,形象直观地获取动态隙角。如果改变灭茬机组运动性能参数,可立刻得到新的动态隙角。将灭茬刀及刀盘建立三维模型,建立相关尺寸的动态关联关系,得到三维模型并进行装配及干涉检查。进行了运动仿真分析,结果表明,符合设计要求,为仿生灭茬刀辊提供了新的设计方法及分析方法。To improve the reliability and efficiency of the design of stubble crushing blade roller, the dynamic gap angle was visualized by drawing the trajectory of the blade cutting-edge using UG-NX3 software. New dynamic gap angle can be obtained by changing the kinematic parameters of the stubble chopper. 3D models of stubble crushing blade and blade disc were built to obtain the dynamic relationships among related dimensions. The 3D models were assembled and their interpositions were checked. Kinematic simulation analysis was conducted and results show that the original design requirement was satisfied. This provide a new design and analysis method for bionic stubble roller.
