基于AMESim的支架回撤吊车工作液压系统设计与仿真分析

摘要

Safe,fast and efficient removal process is particularly important for the modem large mine production.The shield mule is a large equipment used for hydraulic support's withdrawal in the relocation process.We complete the design of the support retracement crane working hydraulic system,including lifting and swinging hydraulic system,hydraulic system.And modeling and simulating of the hydraulic system by AMESim,we obtain the output characteristic and parameters of the hydraulic cylinder work component.The results show that the hydraulic system can well meet the performance requirements of stents retracement crane.%安全、快速、高效的搬迁工艺对于现代化大型矿井的生产推进尤为重要,支架回撤吊车是搬迁工艺中用于完成液压支架撤离的大型设备.设计完成了支架回撤吊车的工作液压系统,包括吊运液压系统和摆动液压系统,并利用AMESim对液压系统进行了建模及仿真,得到了工作元件液压缸的输出特性和参数.结果表明,该液压系统能够很好的满足支架回撤吊车的使用性能要求.
