An Energy-saving Design of Hydraulic Cylinder Based on Life Cycle and Modularization

To quantitatively analyze the energy-saving design of hydraulic cylinder, the energy consumption in the whole life cycle is considered as the research object. Combining life cycle with modularization analysis, a topological structure of hydraulic cylinder is built according to the extenics theory, and the concept of energy-saving design unit is put forward. The indexes of cost, environment and efficiency are considered to analyze and evaluate energy-saving design unit step by step to obtain the optimal design scheme of energy saving. The results show that this method can accurately evaluate the synthetical indexes of energy-saving design unit at different levels and effectively control the energy consumption. Finally, the cylinder of a particular model hydraulic cylinder is taken as a case, by which the life cycle stage of parts machining is analyzed to prove the feasibility and practicability of the method.
