Analysis of dynamic characteristics of longitudinal cutting part of cantilever roadheader

该文简单分析了掘进机截割部的构造,对截割头进行了运动学分析,简化了其运动轨迹,另外对悬臂摆动机构进行了运动分析。最后,对截割头在工作状态时进行了动态特性分析,特别分析了摆动力和截割力之间的关系,推算出了它们之间的匹配系数。

This paper the structure of the cutting part of the heading machine is simply analyzed, the kinematics analysis is carried out on the cutting head, and the motion trajectory is simplified. In the end, the dynamic characteristic analysis of cutting head is carried out, and the relationship between the force and cutting force is analyzed, and the coefficient of the matching between them is calculate
