Simulation Study on a Parallel Hybrid System of Hydraulic Excavator

Abstract:

Based on low utilization rate of energy and high fuel consumption, a parallel hydraulic & electric configuration for hybrid excavator was proposed according to the capacitor and motor. The mathematical model of key components such as engine, electric motor, and capacitor were established. For the hybrid power system based on SUNWARD 20T hybrid excavator, the paper established simulation model and analyzed the energy saving effect of hybrid system by simulation based on the actual load spectrum of hydraulic excavator as input signal. The results indicate that adopting the parallel hybrid system are helpful to improve the energy saving effect of hydraulic excavator, and the energy saving efficiency is about 23.6%.
