摘　　要：为便于实验室研究大惯量液压回转系统的控制特性,建立了大惯量液压回转模拟系统与实际系统参数匹配的理论基础,并指出应分别按照泵排量、马达排量、转动惯量三者之间的关系来匹配模拟系统的参数,并以300 t矿用液压挖掘机的回转系统为例,对模拟系统的参数进行了匹配。结果表明:模拟系统与实际系统具有相似的动态特性。To study the control characteristics of hydraulic rotary systems with large inertia,the foundation of parameter matching between hydraulic rotary simulation systems and actual systems with large inertia was established,and it was pointed out that the parameters of simulation system should be configured by the relationship of pump displacement,hydraulic motor displacement and inertia.At last,the 300 ton hydraulic excavator＇s rotary system was taken for example,the parameters of the simulation system were matched with the actual system. The result shows that the simulation system has similar dynamic characteristics of the actual system.
