摘　　要：为改善工程机械自动怠速系统性能,针对纯电驱动工程机械提出一种基于液压蓄能器的负载压力适应型自动怠速系统,分析了新型自动怠速系统结构和工作原理。考虑到系统的节能效率和操控性能,提出了具有负载压力适应功能的自动怠速分段控制策略,并建立AMESim-MATLAB/Simulink的联合仿真模型进行研究,最后基于所搭建的试验平台展开试验研究。结果表明:所提出的新型自动怠速分段控制策略可行,且分段控制效果明显。In order to improve the idle speed control performance of construction machinery, an automatic idle speed control system of load pressure adaptation based on hydraulic accumulator is proposed for electric-drive con- struction machinery. The characteristics and working principle of the proposed system are analyzed. Giving consid- eration to the recovery efficiency and operation performance, a novel automatic idle speed subsection control strate- gy of load pressure adaptation is put forward. The characteristics of the subsection control system are analyzed with the co-simulation of AMESim and MATLAB/Simulink. Finally, a test rig is constructed to study the subsection con- trol strategy. The results show that the subsection control strategy of the novel system is feasible, and the subsection control effect is obvious.
