为确定纵轴式掘进机截割头移动速度与转速的最佳匹配关系,对不带伸缩机构截割头截齿的运动规律进行分析,提出了相关截齿轨迹、半相关截齿轨迹和不关截齿轨迹3种轨迹形式,并利用SolidWorks的VBA语言开发出截齿轨迹相关性分析软件LCkam。对不带伸缩机构的截割头上所有截齿轨迹的模拟结果表明:通过分析截割头上各截齿的运动轨迹,可以计算并绘制出该种截割头移动速度v与转速的n匹配关系图,利用v-n图能够确定处于不同转速条件下截割头移动速度的合理范围。

In order to determine the optimum matched relationship between the moving speed and rotary speed of the cutting head on the longitudinal shaft type ro adheader, an analysis was conducted on the moving law of the picks on the cutting head with no telescopic mechanism.Three tracing modes as the related pick tracing, semi related pick tracing and no related pick tracing were provided.The SolidWorksDs VBA language was applied to develop the relative analysis software LCkam of the pick tracing.The simulation results of all pick tracings on the cutting head with no telescopic mechanism showed that with the analysis on the moving tracing of each pic k on the cutting head, a matched relationship diagram between the moving speed v and the rotary speed n of the cutting head could be calculated and drawn.The V-n di agram could be applied to determine the rational moving speed scope of the cutting head under the different rotary speed condition.
