摘　　要：提出了一种采用直驱式电液执行器实现双缸同步驱动的液压系统。通过同步原理分析,提出了三种同步方案。基于AMESim仿真软件,搭建直驱式电液执行器驱动双缸系统的仿真模型,完成系统的动态特性、位置跟踪精度及同步性能分析,为直驱式电液执行器在重载工况下采用多执行元件驱动系统的应用提供了有力的理论支持。A new type of double cylinders synchronous system driven by a direct drive electro-hydraulic actuator is put forward in this paper. There are three synchronization schemes are proposed through the analysis of the principle of synchronization. Based on AMESim, the simulation model is built, and the dynamic characteristics, position accuracy and synchronous performance of the system are analyzed. It provides a powerful theoretical support for the application of the direct drive electro-hydraulic actuator in the heavy load operating conditions.
