摘要
Abstract
Aimed at the shortcomings of existing electric rail vehicle,such as poor starting performance,large power impact and short endurance mileage,a new type of electro-hydraulic hybrid drive system is developed.A mathematical model of power flow is set up,and a coupling method of the relationship between electric power and hydraulic energy storage power is analyzed and determined.Based on driving conditions under a typical ramp,a power coupling strategy for different driving stages is formulated,and a simulation analysis is carried out by AMESim.The results show that an electro-hydraulic hybrid drive system not only improves starting performance up to 57％ and saves 61.7％ of power consumption in the early stage,but also basically eliminates the impact of electric power and saves 50％ of power consumption in the acceleration stage.关键词
