摘　　要：建立了臂式掘进机新型振动截割机构带载时的力学模型,利用Lagrange方程建立了该机构带载时的运动微分方程组,并根据实际工况对运动微分方程组进行了简化。通过对该机构的动力学分析,得出了截割头带载时的转速及其输出扭矩的运动关系式,比较了截割头带载和空载时运动规律的异同,为进一步分析振动截割机构的运动特性及设计振动截割机构提供了理论依据。The dynamic model of vibra-cutting mechanism of roadheader with load is established. Then its differential equation is set up by means of Lagrange equation, and is simplified according to conventional practice. Through dynamic analysis of the mechanism, the movement relation between velocity of vibra-cutting head and its output torque is drawn, Then similarities and differences of its movement rule with load or without load are compared.All research works offer theoretical basis foundation for more analyzing dynamic characteristic of vibra-cutting mechanism and designing the mechanism.
