摘　　要：基于掘进机在进行截割的过程中,由于煤岩的复杂多变,容易引起截齿的载荷变化,引发截割头振动的问题,针对掘进机截割两种典型的工况,采用非线性的动力学分析软件对横截及钻进两种不同工况下的截割阻力进行仿真分析,获得截齿的受力变化特性,为掘进机的减震设计及优化使用提供参考指导。In the process of cutting,due to the complex and changeable coal rock,the load change of cut-off teeth is easy to cause the vibration of cut-off head.Therefore,for two typical working conditions of cut-off of roadheader,the simulation analysis of cut-off resistance under two different working conditions of cross-cutting and drilling is carried out by using non-linear dynamic analysis software to obtain the force change characteristics of cut-off teeth,which can provide reference guidance for the design and optimization of vibration reduction of roadheader.
