A new logic valve integrated hydraulic system of hydraulic hammer was researched and developed. The “gray-box” modeling method used for large-scale hydraulic system was introduced. By means of the “gray-box” method and the software PMDSHS the modeling and simulation on dynamic characteristics of the hydraulic system in hydraulic hammer was performed. It is shown from practice that the new hydraulic system possesses many advantages and better dynamic characteristics and that the “gray-box” modeling method can be widely used for hydraulic system analysis.
