Abstract

This study evaluates the effect of hybridization on excavator when the hydraulic swing motor of a conventional excavator is replaced by an electric motor. The powertrain structure and the working environment of the conventional system are introduced, and the fuel consumption of the conventional excavator is obtained from experimental data for four specific working schedules. Two structures of hybrid excavators are introduced, and the best fuel consumption is solved by Dynamic Programming, which guarantees the minimum fuel consumption for the same schedules. The results showed that the fuel consumption of the hybrid excavator can be saved by about 9∼17% depending on the working schedules and that the fuel consumption decreases as more electrical power of swing motor is used for rotation.
