摘　　要：以分析履带搬运车功率匹配为基础,提出了一种基于多段一阶线性拟合的万有曲线经济工作线提取方法,根据该方法得出的经济工作线,设计了一种柴油机-HST系统的最优燃料控制复合控制方法。在图形化仿真环境AMEsim中建立了仿真模型,对转速闭环反馈的调速特性仿真结果进行了分析,得出柴油机转速调节图,进而推断出其节能性能。实验结果表明:发动机转速与HST系统的复合控制有效地提高了系统节能性能,是实时调节柴油机工作在经济区域的有效途径。Based on the analysis of power matching between diesel engine and HST,a new curve extraction method based on first-order linear fitting is presented. Based on the most economical working curve obtained with the method,a new fuel optimal control method of diesel engine-HST system is designed. A simulation model is established in AMEsim; speed characteristic in closed loop feedback system is analyzed. The results show that power matching and joint control between diesel engine and HST is an effective way for improving the vehicle' s matching identity and ensure its working point in the economic region.
