摘　　要：根据支架试验台对同步控制系统的要求,通过分析调高油缸及外加载油缸的工作状态和运动特性,提出基于电液比例技术的支架试验台同步控制系统的设计思路与研究方法,并推导出电液比例阀、非对称液压缸等元件的数学模型,建立电液比例同步控制系统的数学模型,提出系统静、动态分析方法及系统校正的方法,为进一步设计与试验提供参考。The working states and moving performances of vertical steering cylinders and external loading cylinders were analysed according to the requirements of the support test-bed for the synchronous system. The design idea and research method of the synchro- nous control system of hydraulic support test-bed were given based on the electro-hydraulic proportional technology. The mathematic models of electro-hydraulic proportional valve, asymmetry hydraulic cylinders and the synchronous system were deduced. The methods of static analysis, dynamic analysis and system correction were given.
