卧式旋耕机弯形刀侧切刃曲线滑切作用的动态分析

THE DYNAMIC ANALYSIS OF SLIDE CUTTING PHENOMENON ON THE SIDE EDGE OF CURVED BLADES ON A HORIZONTAL SHAFT OF ROTARY TILLER

卧式旋耕机弯形刀侧切刃曲线滑切作用的理论分析,尚停留在以前进速度Vm=0为前提下滑切角变化的静态分析,与实际工作中的滑切作用相差甚远。木文提出的旋耕机组在向前运动时旋耕机弯形刀侧切刃曲线滑切作用的动态分析,与实际情况更为接近。

Tradional analysis of slide cutting phenomenon on the side edge of curved blades on a horizontal shaft of rotary tiller was based on the assume that the tiller was in still status. That was different from the actual working status. The dynamic analysis of slide cutting phenomenon on the side edge of curved blades is based on the condition that the tiller is provided a forward speed so the result obtained describes the slide cutting phenomenon more actually.
