The Research Trends and Comprehensive Evaluation of Hybrid Excavator

Abstract:

Article Preview

The energy saving of hydraulic excavator meets it’s bottle-neck. The load characteristic and working condition are analyzed. And the applicable of hybrid power technology which is widely researched on vehicle is introduced. It suggests great effects on energy saving and may break up the bottle-neck. In order to compare the fuel consumption of the three kinds of excavator: normal, series and parallel, the matlab/simulink model of series and parallel hybrid excavator are founded and the load chart is collected from a 5t excavator. Based on simulation results, the two kinds of hybrid excavator are compared from the three aspects: manufacture cost, operation performance and component performance. The results indicate that the parallel configuration with directory electrical motor rotary driving and regeneration rotary braking is the currently main developing program.
