摘要
由于P-Q伺服阀内部的压力反馈作用,使得采用P-Q伺服阀控制的被动式加载系统能取得较好的抑制多余力效果。通过对P-Q伺服阀工作原理的分析,分别建立了P-Q伺服阀和采用P-Q伺服阀控制加载的减摇鳍负载仿真台的传递函数模型。通过对P-Q伺服阀加载试验曲线的分析表明,采用P-Q伺服阀控制可以有效地抑制减摇鳍仿真台的多余力,特别是减摇鳍系统启动和换向时的多余力。
The passive loading system controlled by P-Q servo-valve can eliminate superfluous force because of the Pressure feedback of P-Q servo-valve. The transfer function model of P-Q servo-valve and electrohydraulie load simulator with P-Q servo control were set up through the analysis of P-Q servo-valve working principle. Through the comparison of experimental loading curves of load- ing system controlled by P-Q servo-valve, it is indicated that P-Q servo-valve can effectively eliminate superfluous force, especially starting and changing directions.
