摘要: 截割部是滚筒采煤机最重要的组成部分,也是最易产生失效的部分。针对现有滚筒采煤机截割部可靠性低和适应性差的问题,设计一种高可靠性机电液短程截割传动系统,该系统实现了负载突变下的缓冲减振和煤层变化下的滚筒调速。建立截割电动机、泵控马达系统和蓄能器的数学模型,基于AMESim软件建立MG300采煤机截割传动系统的仿真模型并进行系统调速性能、应对突变工况性能仿真分析和效率分析,结果表明系统既能实现滚筒转速的良好调节又具有一定的缓冲减振功能并且在典型工况下有着较高的传递效率。因此,所设计系统能提高采煤机的可靠性和自适应性,仿真结果验证了该方案的有效性和可行性,为深部危险煤层无人采煤机的研发奠定了基础。

Abstract: The cutting unit is the most important component of the shearer, but it is also the part that produces failure easily. Aim at solving the shearer’s low reliability and poor adaptability, a new kind of high reliability electromechanical-hydraulic short-range cutting transmission system is designed. The system can realize buffering and damping with the load’s mutation and the roller speed can be controlled with the variation of coal seam. The mathematical models of the cutting motor, the pump control motor system and the accumulator are established. The simulation model of MG300 shearer cutting transmission system is established based on AMESim software. The efficiency and the performance of speed regulation and coping with the load’s mutation are analyzed by the simulation. The results show that the system can not only regulate roller speed well but also process the buffering and damping function and keep high transmission efficiency in the typical working conditions. Consequently, the system can improve shearer’s reliability and adaptability. The simulation results illustrate the effectiveness and feasibility of the program which lays the foundation for the design and optimization of the cutting transmission system of shearer.

Key words: buffering and damping, cutting transmission system, roller speed regulation, shearer
