| 摘 要： | 以DN63位移随动式超高压比例插装阀为研究对象，考虑摩擦力与伺服阀阀口流量，对其先导部分与主阀部分进行机理建模。通过分析压力和温度变化引起的油液密度和黏度的变化规律来修正机理模型参数，从而提高模型的准确性。利用Simulink对模型进行仿真和试验测试,结果显示两者基本一致，从而验证了模型的正确性。

| Abstract: | Taking the DN63 displacement-follower ultra-high pressure proportional cartridge valve as the research object, considering the friction forces and the flows of the valve mouth, the mechanism of the leading part of the displacement servo valves and the main valve parts was modeled respectively. Density and viscosity changing rules of oil caused by ultra-high pressure and temperature changes were analyzed, and the mechanism model parameters were modified to improve the accuracy of the model. The model was simulated by Simulink and was tested by experiments. The results of simulations and tests show that both of them are nearly the same, which verifies the correctness of the model. |
