摘要
在设计和研究抓具系统的功能和各种特性时,首先必须对抓具颚爪的抓取曲线进行研究。本文分析和论述了抓具的抓取轨迹曲线、影响抓取轨迹曲线的因素以及抓取曲线的绘制。
This paper discrebes the grab track curves and its drawing methods. The curves are as continuous smooth curve and are composed of vertical segement. The affecting factors of grab track curve are the model of grab track constructure, the characters of resistent variation in grab and the type of grabed materials.
