Abstract

There are some problems in the synchronous control system of electro-hydraulic servo double hydraulic cylinders, such as uncertainty of system parameters, time variation, difference between two subsystems, and unbalanced load disturbance during operation. The above problems cause the output responses of the two cylinders to be inconsistent, resulting in the situation that the output flows of the two cylinders are not synchronized. Further improve the accuracy of synchronous control while reducing the cost of using synchronous control system. The AMEsim simulation model of electro-hydraulic servo dual-cylinder synchronous control system is established, and based on this model, the dynamic characteristics, coupling characteristics, and synchronization characteristics of the double-cylinder system are analyzed theoretically and simulated. Analyze and verify the influence of various factors on the synchronization of double hydraulic cylinders, and summarize the influence law of the change of different factors on the output and synchronization accuracy of the double hydraulic cylinder system. This study analyzes the influence of various factors on the synchronization of double cylinders by adjusting the parameters, and summarizes the influence law of the change of different factors on the output and synchronization accuracy of the double cylinder system.

双液压缸位置同步控制系统特性研究

电液伺服双液压缸同步控制系统存在系统参数的不确定性、时变、子系统间的差异以及运行过程中负载不平衡扰动等问题。以上问题导致两个气缸的输出响应不一致，导致两个气缸的输出流不同步的情况。进一步提高了同步控制的精度，同时降低了使用同步控制系统的成本。建立了电液伺服双缸同步控制系统的AMEsim仿真模型，并基于该模型对双缸系统的动态特性、耦合特性和同步特性进行了理论分析和仿真。分析验证了各种因素对双液压缸同步的影响，总结了不同因素变化对双液压缸系统输出和同步精度的影响规律。本研究通过调整参数，分析了各种因素对双缸同步的影响，总结了不同因素的变化对双缸系统输出和同步精度的影响规律。
