混合动力工程机械节能效果评价及液压系统节能的仿真研究

对比了串联和并联混合动力在工程机械中的节能效果，并分别将马达能量回收、单独驱动、电动机直接驱动回转和进出口独立调节等节能措施与并联混合动力系统相结合，进行了燃油消耗的理论计算和节能效果的评价，其结论对工程机械的节能研究具有指导意义。考虑到生产成本、操作性和元件的性能等方面因素的影响，提出并联混合动力单独驱动进出口独立调节电驱回转系统应该是目前比较切实可行的主要开发方案。

EVALUATION FOR ENERGY SAVING EFFECT AND SIMULATION RESEARCH ON ENERGY SAVING OF HYDRAULIC SYSTEM IN HYBRID CONSTRUCTION MACHINERY

Energy saving effects of series and parallel hybrid applied in construction machinery are compared. Theoretical calculation of fuel consumption and evaluation of energy saving effect are implemented to a system combined by motor energy regeneration, separate driving, electrical motor directly driving rotary actuator, meter-out control and parallel hybrid system. The results can be used to direct the research on energy saving in construction machinery. Considering the factors of manufacturing cost, operation performance and component performance, etc, a new system combined by all above mentioned methods except for motor energy regeneration is put forward as the current main developing program.
