Title: Research on Energy-saving for Hydraulic Excavators Based on Energy Flow Analysis
Abstract: In order to evaluate the performances of existing hydraulic excavators,and find out effective ways of energy saving and emission reducing,a whole excavator simulation model was built up with Simulink and SimMechanics toolboxes of MATLAB system based on a 200kN class excavator.The energy-flow of the hydraulic excavators was analyzed,and the output power of engine and the energy loss of main control valves were simulated.It is shown that,hybrid driving and energy regeneration with hydraulic motor are two effective energy saving projects for hydraulic excavators.
