摘　　要：采煤机的工作环境很恶劣,摇臂转矩轴在采煤机工作中的作用至关重要,分析它在恶劣工况下的相关状态及响应变得十分必要。应用ANSYS Workbench对采煤机摇臂转矩轴进行有限元建模及静态、动态特性分析。通过静力分析得出转矩轴在截割电机功率3倍载荷下的应力、应变分布情况。又根据实际工况对转矩轴进行了瞬态分析,模拟了转矩轴在两种极端工况下的应力、应变以及扭转角的响应,验证了它的保护作用。进而又将静力分析结果与瞬态分析结果进行综合对比分析,对进一步研究转矩轴提供了参考和依据。Shearer ＇s working environment is very bad,the shearer rocker torque shaft play a vital role in mining.It becomes necessary to analyze the relevant state and response in poor condition.Based on ANSYS Workbench,shearer rocker torque shaft in finite element modeling and static,dynamic characteristics is analyzed.Through static analysis,the stress,strain distribution about torque axis in the cutting motor power 3 times are got.According to the actual working conditions of the torque shaft for the transient analysis,the torque shaft stress,strain and torsion angle of the response in two extreme conditions are simulated.The protection effect is verified.Then it is compared about the results of static analysis and transient analysis.It provides reference and basis to further study of torque shaft.
