| 摘 要： | 为了提高电液负载模拟器加载系统的控制性能,并解决多余力抑制这一技术难题,对流量阀单阀控制电液负载模拟器系统和流量阀与P-Q阀双阀并联控制电液负载模拟器系统进行了建模、仿真和试验研究.仿真和实验结果表明:加载系统采用双阀并联控制比单阀控制的多余力明显减小,动态加载精度明显提高.

| Abstract: | The mathematic model of electro-hydraulic load simulator controled by single flow valve and double valve composed by flow valve and P-Q servo valve was set up,the simulation and experimental study on eliminating superfluous force was finished to improve the control precision.The result shows that superfluous force is less in double valve parallel control system than that in single valve control system,and the precision of dynamic loading is increased. |
