摘　　要：液压缸在使用过程中会产生内泄，内泄会使液压阻尼比增大，液压固有频率减小，降低系统的响应速度。采用在线测试上升时间lt、峰值时间tp和调整时间￡的方法判AGC液压缸是否需要下线修复，可避免资金浪费。If the internal leakage happens in the use of hydraulic cylinder, it will make the hydraulic damping ratio high, the natural frequency low and the system response slow. Therefore it＇ s necessary to carry out the on-line inspection of rising time tr, peak time tp and adjusting time tn to determine whether the AGC hydraulic cylinder has any internal leakage and whether it has to be taken off the line for repairing in order to avoid fund wastage.
