建立了掘进机刀盘的三维有限元模型,对以前学者研究中的一些细节进行了考虑,并进行了研究,通过分析结果得出:刀盘的应力、应变主要集中在刀盘的中心区域,其值符合条件。模态分析表明不会出现共振现象。通过这一研究对于在采煤工作中刀盘的正常运行与优化具有指导意义。
The three-dimensional finite element model of the cutterhead of the roadheader is established. Some details of the former scholars’ study are considered and studied. The results show that the stress and strain of the cutterhead are mainly concentrated in the center of the cutterhead, Its value meets the conditions. Modal analysis shows that no resonance occurs. Passing this research is instructive for the normal operation and optimization of cutterhead in coal mining.
