伺服液压缸压下系统动态特性测试方法研究

Dynamic characteristics test system for Servo hydraulic cylinder

拥有良好性能的伺服液压缸在液压行业的应用日趋广泛,探索液压缸性能的检测方法有着实用意义。针对某大型钢厂的液压压下伺服系统进行无负载测试,开发了研究伺服液压缸闭环频域响应特性的计算机辅助测试系统。实践证明此测试方法操作简单,测试结果准确,有广泛应用前景。

Hydraulic system performance depends on hydraulic cylinder to a great extent,so the inspection and test of the hydraulic cylinder has very important practical significance.In this paper,combined with a large steel mill of hydraulic pressure servo system,use computer aided testing system to analyze closed loop frequency response of servo hydraulic cylinder.It is a test without load for closed loop system dynam-ic characteristics.Practice has proved that this test system is simple with accurate result,and it has a wide application prospect.
