The Acquisition of Natural Frequency & Damping Ratio of the Valve-controlled Cylinder System
LI Jian-rong
Abstract：As for the valve-controlled cylinder system within hydraulic servo control system,the wrong derivative of pressure with respect to time results in wrong hydraulic natural frequency and damping ratio of the system,which influences dynamic analysis of the system. The paper analyzes the cause of and presents a correct solution to the acquisition of the natural frequency and damping ratio to improve the accuracy of hydraulic control system design and fault diagnosis.
