Research on the Energy Saving Effect of Working Devices on Parallel Hybrid Loader

Abstract

In order to increase the energy saving effect of hybrid loader, a power system applied to parallel hybrid loader is proposed. The system structure, working condition characteristics and control strategy of hybrid loader are analysed, and the energy saving effect of working devices is studied. The parameters of the main components of a 5 tons hybrid loader are changed and simulated to find the best when working devices working or not. The simulation results demonstrate that the system installed the influence of working devices on fuel consumption, and whether using working devices causes some differences under dynamic rule-based control strategy. The volume of accumulator are the same while the displacement of pump/motor in hydraulic brake regeneration system using working devices should be bigger than the system under stopping working devices which means the condition of working devices is not negligible in the process of parameter matching for parallel hybrid loader .
