摘要
为驱动大负载实现往复运动,多采用高功重比的液压驱动系统来实现,针对采用压力油箱供油的液压驱动系统即气液联动系统进行机理分析,并对其中各元部件进行数学建模,形成整个气液联动系统仿真模型,并探究关键元件压力油箱的工作机理及其工作特性。通过搭建加载系统进行加载分析,并搭建加载系统数学及仿真模型,通过气液联动系统与加载系统联合仿真模型进行仿真分析。考虑了温度对液压油的影响,实现了对压力油箱的精准建模,通过仿真与实验平台的对比,验证气液联动系统及其加载系统仿真模型的准确性,可为液压驱动系统实际设计与特性分析提供理论基础。
In order to drive the large load to achieve reciprocating motion,the hydraulic drive system with high power-to-weight ratio is often used to realize it.In this paper,the mechanism of the hydraulic drive system,namely the gas-liquid linkage system,is analyzed,and the mathematical modeling of each component is carried out to form the simulation model of the whole gas-liquid linkage system,and the working mechanism and working characteristics of the key component pressurized oil tank are explored.By building a loading system for loading analysis,and building a mathematical and simulation model of the loading system,a joint simulation model of the gas-liquid linkage system and the loading system is formed for simulation analysis.In this paper,the influence of temperature on hydraulic oil is considered,and the accurate modeling of pressurized oil tank is realized.Through the comparison between simulation and experimental platform,the accuracy of the simulation model of gas-liquid linkage system and its loading system is verified,which can provide a theoretical basis for the actual design of hydraulic drive system and characteristic analysis.
