摘　　要：苗间除草装置是水田除草机的核心部件,其工作时的功率消耗为该机具总功消耗的主要部分。利用自制扭矩传感器测取除草机工作过程中除草刀轴上产生的扭矩。选取影响除草机功率消耗的刀盘转速、机具前进速度、除草作业深度三因素为试验因子,采用二次正交旋转设计方法进行试验研究。运用minitab15.1软件处理扭矩测试结果,根据田间试验分析,得出苗间除草刀在最佳工作状况下产生的扭矩值,该数值可为机具关键部件可靠性分析和寿命估算等提供重要的理论参考。This papal used the sensing technology to obtain the torque in the grubber work process to remove weeds, took the speed of tool pan, the grubber forward speed and the depth in weeding work three factors which affect the power consumption of the grubber as the experimental factors to make the experimental study using the way of the quadratic orthogonal rotation design. Through the data analysis on the minitab15.1 software, discovered its best operating performance interval based on the machine weeding efficiency analytical investigation data result, provide important theoetical reference for the reliability analysis and the life estimation about the key components.
