近年来，由于能源危机的加剧和环境的恶化，挖掘机的节能研究成为一个热门话题。基于公共压力轨道的液压混合动力挖掘机具有功率密度高、环境友好、易于根据现有制造工艺进行改装等优点，为电动混合动力挖掘机提供了一种替代方案。本文重点研究了HHEC的燃油消耗率和执行器的动态响应，以确保新系统在不牺牲性能的情况下实现节能。首先介绍了HHEC的基本原理，然后介绍了HHEC的定标过程，并列出了数学分析和实验辨识相结合的建模周期。仿真结果表明，HHEC具有较快的动态响应，可以被工程所接受，与原来的LS挖掘机相比，油耗降低了21%，采用另一台较小的发动机后，油耗降低了32%。
Energy-saving research of excavators is becoming one hot topic due to the increasing energy crisis and environmental deterioration recently. Hydraulic hybrid excavator based on common pressure rail (HHEC) provides an alternative with electric hybrid excavator because it has high power density and environment friendly and easy to modify based on the existing manufacture process. This paper is focused on the fuel consumption of HHEC and the actuator dynamic response to assure that the new system can save energy without sacrificing performance. Firstly, we introduce the basic principle of HHEC; then, the sizing process is presented; furthermore, the modeling period which combined mathematical analysis and experiment identification is listed. Finally, simulation results show that HHEC has a fast dynamic response which can be accepted in engineering and the fuel consumption can be reduced 21% to compare the original LS excavator and even 32% after adopting another smaller engine.
