一种 AGC 伺服液压缸内泄漏的实验测试方法

摘要

内泄漏是影响 AGC 液压缸动静态性能的主要因素之一。针对 AGC 伺服缸内泄漏测试方法，通过对比分析多种实验方法，设计了 AGC 伺服缸内泄漏实验测试方案，搭建了液压缸内泄漏测试实验台，得到了实验曲线，并对实验数据进行分析拟合得出了伺服缸内泄漏量的计算式。%Internal leakage is one of the main effecting factors of AGC hydraulic cylinder.In this paper,the leakage mathematic model of the hy-draulic cylinder was established;experimental methods were designed;the experiment rig was es-tablished.Cylinder’s internal leakage curves were obtained,and experimental calculating equitation was acquired.
