传统设计方法在高速曲柄摇杆式分插机构设计上存在不足。该文对该机构进行了弹性动力学分析 ,结合运动精度改善法及优化方法 ,对该机构栽植臂端点的栽插精度进行动态误差补偿 ,显著降低了栽植臂端点在关键工作位置的失真量 ,并减少了机构的质量 ,为高速曲柄摇杆式水稻插秧机分插机构设计提供了一种思路。 The traditional design method has some shortcomings in the design of high-speed crank rocker sticking mechanism. In this paper, the mechanism was analyzed by elastic dynamics. Combined with the improved method of motion accuracy and optimization, dynamic error compensation was made on the planting accuracy of the end of planting arm. The distortion of the end of planting arm at the key working position was significantly reduced, And reduces the quality of the mechanism, providing a train of thought for the design of the high-speed crank-rocker rice transplanter sub-racking mechanism.
