| Abstract: | A Short-stroke digital hydraulic servo cylinder d esigned with the principle of donble-degree freedom overcomes some shortcomings of the traditional stepper ones . A linear model is established in the paper and then its static-stiffness and stability are analyzed. Based on theoretical, the ranges of key structural sizes are determined to ensure that the digital hydrau lic servo cylinder has a better static and dynamic performance. |
