摘要:

基于流体管路线性摩擦模型,运用流体传输管道动力学及液压控制系统相关理论,针对油源与控制阀间具有长管路的某水下作业装置液压控制系统,建立了考虑管路效应的阀控非对称缸液压系统数学模型。利用AMESim软件建立了仿真分析模型,从理论和仿真角度分析了管路效应对系统动态特性的影响;通过在进油和出油管路与控制阀接口处配置相匹配的蓄能器,初步消除了管路效应的影响。

Abstract:

For a hydraulic control system of an underwater device with long pipelines between hydraulic source and control valve, a mathematical model of valve-controlled asymmetric cylinder based on linear friction model was established by applying pipeline dynamics and the related theories.A simulation model was constructed based on AMESim and the effects of pipeline for system dynamic characteristics were studied. It shows that installing suitable accumulators at interface of inline, return line and control valve can eliminate the adverse effect of pipeline preliminary.
