Digital simulation research on dynamic characteristics of symmetrical hydraulic cylinder controlled by four-way valve system

The models of dynamic characteristics of symmetrical hydraulic cylinder controlled by symmetric four-way valve are established. The flexible simulation model is also constructed by the use of MATLAB. The model's dynamic characteristics are Stimulated. It provides the fast analysis method for this kind of systematic design by contrasting different parameters which affect system performance. And around the origin a group of good parameters are found for the dynamic performance of the system.
