针对传统定截速长壁采煤机截割传动系统(LSCT)的缺点，提出了一种新型变截割速度长壁采煤机截割传动系统(LSCT-V)。在AMESim中建立了包括切割电机转子和滚筒的LSCTV和LSCT的动态模型，并使用AMESim分析了每个系统的动态响应。仿真结果表明，与阶跃扭矩负载下LSCT系统的动态行为相比，所设计的LSCT-V系统能够实现频率控制功能。在恒定或变化的切削速度下工作时，LSCT-V 系统的动态特性非常接近。
A new longwall shearer cutting transmission system with variable cutting speed (LSCT-V) is presented to overcome the weaknesses of the traditional longwall shearer cutting transmission system (LSCT) with constant cutting speed. The dynamic model of the LSCTV and LSCT, which includes a cutting-motor rotator and drum, are established in AMESim, and the dynamic response of each system is analyzed using AMESim. Simulation results show that the function of frequency control for the designed LSCT-V system can be achieved, compared with the dynamic behavior of LSCT system under step torque load. The dynamic characteristics of the LSCT-V system are very close when working in constant or varying cutting speeds.
