摘　　要：针对目前采煤机开采作业虚拟仿真大多根据预设轨迹进行三维仿真、较少考虑煤层负载影响、不能展现采煤机运行动态过程的问题,利用LabVIEW与Simulink的交互式程序开发技术,将采煤机开采作业的三维仿真、电气与液压系统仿真、具体工况三者有机结合起来,设计了采煤机开采作业机电液一体化虚拟仿真平台。在煤层负载突变工况下,通过对电气调速系统、液压调高系统的控制,实现滚筒转速和牵引速度自动调整,从而降低滚筒负载。测试结果表明:该平台能精确、形象地展现采煤机运行的动态过程与煤层负载突变工况下的控制过程。在采煤机操作培训中,该平台能帮助采煤机操作人员掌握煤层负载突变工况下的采煤机控制策略,避免实操风险。In view of problems that current virtual simulation of shearer mining operation are mostly based on preset trajectories, seldom consider impact of coal seam loading and can not show dynamic process of shearer operation, three-dimensional simulation of shearer mining operation, electrical and hydraulic system simulation, and specific working conditions are combined to design electromechanical and hydraulic integration virtual simulation platform for shearer mining operation using LabVIEW and Simulink interactive program development technology. Under condition of sudden change of coal seam load, the drum speed and traction speed are automatically adjusted to reduce the drum load through the control of electric speed control system and hydraulic height adjusting system. The test results show that the platform can accurately and visually display dynamic process of shearer operation and control process under condition of sudden change of coal seam load. In the shearer operation training, the platform can help shearer operator to master shearer control strategy under condition of sudden change of coal seam load to avoid actual operation risk.
