摘　　要：针对采煤机截割部传动系统动态特性问题,从刚柔耦合多体动力学理论出发,根据采煤机截割部传动系统的传动原理和结构参数,对采煤机截割部传动系统动态特性问题进行研究。以RecurDyn软件为仿真平台建立了采煤机截割部齿轮传动系统刚柔耦合动力学模型。模型充分考虑传动轴各方向的柔性特征,以滚筒三向截割力为激励载荷,计算出传动系统中各齿轮啮合力、各轴应变及轴承连接处的接触。研究结果表明:第11对齿轮啮合力最大,为11 272 634.4N。轴承最大接触力发生位置为轴5上的轴承1,为912 317.98N。研究结果为传动系统的优化设计及疲劳寿命预测提供依据。On the basis of the theory of rigid-flexible coupling multibody dynamics as well as the transmission system of coal winning machine cutting part the transmission principle and structure parameters,the dynamic characteristics of coal winning machine cutting part drive system was researched for the problem about dynamic characteristics of coal winning machine cutting part the transmission system. The rigid-flexible coupling dynamics model of coal winning machine cutting part for gear transmission system was built in Recurdyn software environment. To the cutting force in drum three loads,Transmission Model was under full consideration of the flexible drive shaft in all directions feature and calculated the gear meshing force,strain and bearing junctioncontact. Results showed that 11 th gear mesh together is the biggest,11272634. 4N. The maximum contact force,912317. 98 N,is measured at the place of the shaft 5 bearings 1. Results provide a basis for optimum design of the transmission system and prediction of fatigue life.
