摘　　要：以LGM5024原料立磨、LGMS4624矿渣立磨为研究对象,建立了其主辊蓄能器-液压加载系统的模型,推导出了加载系统的液压弹簧刚度公式,并在AMESim中建立了液压加载系统的仿真模型,通过软件仿真直观显示了油缸泄漏系数、油缸工作面积、两腔蓄能器容积、充气压力等因素对加载系统的影响,进而分析了相关参数的影响趋势并得出结论,对此类蓄能器-液压加载系统的设计、改造、调试都有一定的参考意义。With a LGM5024 vertical mill for raw material and a LGMS4624 vertical mill for slag as the research object, the paper established the model of main roller accumulator and hydraulic loading system, and deduced the formula of the stiffness of hydraulic spring of the loading system. In addition, the simulation model of the hydraulic loading system was built in AMESim, and the influences of cylinder leakage coefficient, cylinder working area, accumulator volume of two cavities and gas charge pressure on the loading system were displayed via simulation. And then, influence tendency of relevant parameters was analyzed and conclusion was obtained, which had some reference for the design, reconstruction and commissioning of the kind of accumulator and hydraulic loading system.
