| Abstract: | In order to develop high-efficiency and energy-saving excavators, the weaknesses of existing excavator hydraulic systems are analyzed to promote the energy utilization ratio. In this manner, a constant-pressure-network readjustment technology, together with its strengths, is explored for excavator hydraulic system design. Based on the working conditions of specific excavators, the energy consumption analysis and comparison are conducted on three hydraulic control systems. It is proven from experimental results that the proposed system possesses technological feasibilitv and energy-saving efficiency. |
