摘要
建立了采用P-Q伺服阀控制加载的电液负载模拟器系统键图模型,并通过仿真验证了该模型的正确性。通过对P-Q伺服阀和普通的流量伺服阀加载试验曲线的对比分析表明,采用P-Q伺服阀控制可以有效地抑制多余力。
Bond graph model of electro-hydraulic load simulator controlled by P-Q servo-valve was set up.It's testified by simulation.Through the comparison with experimental loading curves of loading system controlled by P-Q servo-valve and flow servo-valve respectively,it is indicated that the former can effectively eliminate superfluous force.
