摘要
针对液压支架护帮的支护速度问题,研究了护帮速度控制与采煤机截煤速度的匹配关系,建立了护帮千斤顶节流优化控制AMESim仿真模型,仿真结果表明可通过对护帮千斤顶运动速度的优化控制实现护帮及时支护,为提高支架护帮支护系统的可靠性,满足采煤机安全高效生产提供了一定的理论基础。
To solve supporting speed problem of hydraulic support flipper,the match relations between flipper speed control and shearer broken coal speed control are analyzed,the AMESim simulation model of jack throttle optimization control for hydraulic support flipper is established,the simulation results show that flipper can be supported timely by jack speed optimization control,which provide certain theory basis to meet miner safety and high efficiency production and improve reliability of system.
