Energy-Saving System for Hybrid Hydraulic Excavators

摘要

摘要: 为了降低中型传统液压挖掘机的能耗，减少碳排放，在分析传统液压挖掘机系统能耗点的基础上，结合当前节能方法，提出了带能量回收的油电混合动力系统和油液混合动力系统.根据23 t液压挖掘机的参数配置，建立了传统液压挖掘机、油电混合动力和油液混合动力3种系统回转机构的数学模型，并用AMEsim软件进行仿真，在相同负载工况下，得到了3种回转机构的角位移、角速度、功率和能耗曲线.研究结果表明：油电混合动力和油液混合动力的回转系统比传统回转系统在角位移和角速度方面响应快速、准确，油电混合动力比油液混合动力响应更快；从能耗方面看，油电混合动力和油液混合动力比传统液压系统节能分别达到了42%和28%.

Abstract: To reduce energy consumption and carbon emissions of medium-sized hydraulic excavators, a hydraulic-electric hybrid power system and a hydraulic-hybrid power system, both with energy recovery equipment, were devised in combination with the current energy-saving method after the energy-consumption characteristics of the traditional hydraulic excavator system were analyzed. According to the parameter configuration of the 23 t hydraulic excavator from a company, three kinds of mathematic models of slewing mechanism were set up, i.e., the traditional hydraulic excavator system, the hydraulic-electric hybrid system, and the hydraulic hybrid system. The AMEsim software was used to calculate the models in the condition of the same load, and the characteristic curves of the angular displacement, angular speed, power and energy-consumption were analyzed. The results indicate that in terms of the dynamic response of angular displacement and speed, the two hybrid slewing systems are more rapid and accurate than the traditional hydraulic system, and the hydraulic-electric hybrid system is faster than the hydraulic hybrid system. Compared with the traditional hydraulic power system, the hydraulic-electric and hydraulic hybrid power systems obtain an energy-saving index of 42% and 28%, respectively.
