摘　　要：建立了基于UG的采煤机截割部模型,分析了截割部传热关键件的热源,冷却系统和润滑系统的工况,对截割部稳态温度场进行了基于ANSYS的温度场仿真。搭建2 000 kW功率的采煤机摇臂试验台,进行模拟加载试验并与仿真结果进行对比。试验结果表明:该仿真方法可行,仿真误差<5%。Establish 3D model by UG. Analysis of the heat source by key components, combined with the situation of cooling system and lubrication system. Using ANSYS as the simulation platform, analyses the steady state thermal field of the cutting part. Set up the 2 000 kW cutting part test bench to do experiment, obtain thermal balance temperature on rocker＇s key part compared with the simulation results. The results show that the simulation results is correct, error less than 5%, and this method of analysis is feasible
