摘　　要：以某型号液压挖掘机为研究对象,运用AMESim软件建立液压挖掘机工作装置及其负载敏感液压控制系统模型,并通过该软件进行挖掘、回转、卸载工况下的仿真分析。以某型号挖掘机为研究对象,对其进行挖掘、回转、卸载工况仿真分析,验证仿真模型的设计正确性,分析负载敏感液压控制系统的优势。此基于AMESim软件建立的负载敏感液压控制模块系统的仿真设计可以为以后挖掘机新产品开发中相关工作机构和液压系统的匹配设计奠定基础,同时也可对现有产品的机构工作效率、能量消耗、故障情况进行分析研判。Taking a hydraulic excavator as the research object,the software AMESim is used to establish the models of the working device of the hydraulic excavator and its load sensing hydraulic control system,and the simulation analysis under the conditions of excavation,rotation and dumping is carried out by using this software.Taking an excavator as the research object,the working conditions of excavation,rotation and dumping are simulated and analyzed to verify the design correctness of the simulation models and to analyze the advantages of the load sensing hydraulic control system.The simulation design of the load sensing hydraulic control module system based on software AMESim can lay a foundation for the matching design of relevant working mechanisms and hydraulic systems in the development of new excavator products in the future,and can also analyze and judge the working efficiency,energy consumption and faults of existing products.
