摘要
该文针对某装备用液压伺服作动器在测试过程中表现出的内置线位移相频特性滞后于角位移传感器1°～2°的问题进行了分析。通过建立数学模型进行仿真分析和试验验证,得出了相频滞后问题是由于内置线位移传感器传动连接环节刚度较差和连接环节存在间隙等非线性因素引起的。最后,针对这两个主要因素,采取加强连接环节刚度和减小连接环节间隙的措施进行了试验验证。
In this paper,a hydraulic servo actuator equipped with built-in line displacement sensor showed in the testing process of the lag phase frequency characteristic of angular displacement sensor for 1～2 DEG problem is analyzed..By establishing a mathematical model for the simulation analysis and experimental verification, the obtained phase frequency lag is due to built-in linear displacement transducer transmission link poor stiffness and links to gap caused by nonlinear factor. Finally, according to the two main factors, take the strengthening connection link stiffness and reduce the gap measures is verified.
