摘要
从混合动力液压挖掘机的结构入手,以系统全局效率优化为目标,提出了并联式混合动力液压挖掘机动力源单元和能量储存单元的优化目标函数、约束方程以及整机的参数匹配方法,并结合一台5 t混合动力液压挖掘机系统进行了部件参数匹配的实例研究,通过Matlab/Simulink建模分析得到经参数匹配后的系统,其各部件具有装机功率低、效率高、油耗低的良好特性。
In order to optimize the efficiency of a parallel hybrid hydraulic excavator （PHHE）, this paper firstly get started with the analysis of the system＇s structure, and then the optimal objective function and constraint equations that depict powertrain unit and energy storage unit for PHHE were put forward along with a parameter matching method for the machine. For the purpose of component sizing and matching in PHHE, one case was done in a 5 ton hybrid excavator, and the system with the designed parameters of components could reduce components＇ peak power, increase system efficiency and decrease fuel consumption rate by using Matlab and Simulink toolbox.
