摘　　要：分析了液压同步回路的类型、基本工作原理及特点,指出了影响液压启闭机同步精度的主要因素,对液压启闭机的同步控制策略及几种同步控制方案进行了分析比较,探讨了进一步提高同步精度和同步系统稳定性的措施。The common types, working principle and technical characteristic of the hydraulic synchronous circuit were intro- duced. The essential factors affecting synchronization precise of the hydraulic hoist were indicated. The control strategies and programs of the hydraulic hoist were compared. Further more, several measures improving the synchronization precise and stability were discussed.
