摘　　要：对两机联动1800 t提梁机驱动同步控制技术进行研究,介绍常用液压同步控制方法;根据1800 t提梁机的驱动方式和工作特点选择主从控制策略,设计出双提梁机同步行驶的压力和速度双闭环PID控制器,并通过仿真和试验验证使用此控制器可以满足两机联动提梁机的同步控制精度,且在同步行驶的过程中压力基本保持一致。Synchronous control technology for driving two linked 1800 t girder cranes is studied,and the commonly used hydraulic synchronous control methods are introduced.Based on the driving mode and working characteristics of the 1800t girder crane,a master-slave control strategy is selected,and a pressure and speed dual-closed-loop PID controller for synchronous travelling of the two girder cranes is designed.Simulation and tests have verified that the use of this controller can meet the synchronous control accuracy of the two linked girder cranes,and the pressure is basically consistent in the process of synchronous travelling.
