Static characteristics of digital servo cylinder designed by using helix mechanism have been analyzed.In order to make the structural parameters more compatible with characteristics,an analysis based on simulation was conducted by utilizing Matlab.According to the results obtained,the effects of various structural parameters on stiffness and zero position leakage were discussed,a modification system was designed and some proper structural parameters were determined preliminarily. As a result, under these structural parameters,the digital cylinder possesses a good static characteristics,especially near to a full load,its characteristics and application value are better than those of the conventional one.
