摘要
以负载敏感电液比例多路阀为研究对象,分析了应用于大型联合收割机割台升降控制的电液比例多路阀的工作原理和结构特点,设计了电液比例多路阀结构。通过AMESim的HCD模块对负载敏感多路阀及联合收割机割台升降液压系统进行了仿真分析,得到割台工作的基本动作曲线,使模型能够真实模拟大型联合收割机割台升降系统的实际工况,旨在验证负载敏感系统应用于割台升降液压系统的可行性和节能性。
Taking the load sensitive electro hydraulic proportional multiway valve as the research object,this paper analyzes the working principle and structural characteristics of the electro hydraulic proportional multiway valve applied to the lifting control of the cutting platform of the large-scale combine Harvester,and designs the electro hydraulic proportional multiway valve structure.Through AMESim’s HCD module,the loading sensitive multiway valve and the combine Harvester’s cutting platform lift hydraulic system are simulated and the basic action curve of the cutting platform is obtained,so that the model can truly simulate the application of the large combine Harvester’s cutting platform lifting system in actual working conditions.The feasibility and energy saving of the load sensitive system applied to the hydraulic system of cutting platform lifting are verified.
