摘　　要：为了提高液压启闭机系统的双缸同步精度,采用磁致伸缩传感器检测液压缸行程,使用比例调速阀设计液压同步回路,结合PLC控制程序提高双缸同步精度。实践表明,系统运行的同步效果提高,实时性良好。For enhancing the synchronism accuracy of the dual-cylinder in the hydraulic hoist, a magnetostrictive sensor is adopted to detect the hydraulic cylinder stroke, and proportional speed control valves are used in designing the hydraulic synchronous circuit. The synchronism accuracy of the dual-cylinder is enhanced by combining PLC programs. The result shows that the synchronism of the dual-cylinder is satisfying.
