摘　　要：应用液压模拟加载技术和液压功率回馈试验技术,研究并设计了矿用泵和马达节能型试验系统,对系统的动态加载特性进行了分析研究和AMESim仿真。研究结果表明:试验系统能够进行动态加载并具有显著的节能效果。在动态加载过程中,液压泵和回馈马达的瞬态排量匹配是系统强烈振荡的主要因素,适当调节回馈马达排量控制系统的响应时间可明显减小系统振荡。试验系统采用了伺服阀控马达,具有驱动和制动的双重功能,提升了液压泵和马达传动轴的转速刚度。矿用液压泵和马达功率密度大、使用工况恶劣,应用动态加载和节能技术更贴近工业生产实际,具有实用价值。The test technology of hydraulic simulation loading and hydraulic power recovery are used to design an energy saving test system for mine pump and motor,and the dynamic load characteristics of the test system are analyzed and simulated in AMESim. Research results show that: The test system can be loaded dynamically and has significant efficiency of energy recovery. In dynamic loading process,the transient displacement matching of hydraulic pump and feedback motor is the main factor of strong oscillation of the system,properly adjusting the response time of the feedback motor displacement can significantly reduce the system oscillation. The motor controlled by servo valve has dual functions of driving and braking,which can improve the speed stiffness of the pump and motor transmission shaft. Due to mine hydraulic pump and motor have larger power density and worse working condition,the application of dynamic loading and energy recovery technology is closer to industrial production practice,so the research has practical value.
