Simulation Study On Energy Recovery and Reuse of Hybrid Loader Actuator

Abstract

It is necessary to reduce engine fuel consumption for loaders to overcome the energy crisis faced by today's society. To this end, a hybrid loader arm energy recovery and reuse system is proposed, adding an electrical energy recovery and reuse system to the conventional loader arm system and effectively reducing the loader engine fuel consumption and emissions. The principle of the system is analyzed, the mathematical model of the system components is analyzed, and AMESim models the system. The simulation results show that the system does not affect the regular motion characteristics of the boom arm cylinders. The energy recovery efficiency of the system reaches 58.9 %, and the energy reuse efficiency reaches 86.9 % after four operation cycles. The system can recover energy in hybrid, pure engine, and motor modes. The system's engine provides 24.8 % less energy, engine fuel consumption is reduced by 24.9 %, and pollutant emissions CO, HC, and NOx are reduced by 19.2 %, 25.9 %, and 23.6 %, respectively. The system provides a reference for the research of energy-saving technology for loaders.
