中文摘要:
      针对海上钻井平台上带长管道的水下液压系统进行研究,建立该系统的简化数学模型,对系统的时域响应进行分析。应用AMESim仿真软件对该系统进行建模并分析其动态特性,得出不同管长、管径、油液黏度以及弹性模量条件下的系统响应曲线;分析蓄能器的位置对系统动态特性的影响。利用基于响应面法的Box Behnken试验设计方法分析各因素对系统动态响应时间的影响程度,得出各因素与响应时间的数学模型。对系统进行参数优化设计,得到最佳的管长、管径、油液黏度、弹性模量及蓄能器位置的优化设计方案。优化结果与原设计对比后发现,优化设计的响应时间仅为原模型动态响应时间的349%,极大提高了系统的响应时间,为水下液压系统带长管道系统设计提供了参考。
英文摘要:
      The hydraulic system with a long pipe on offshore drilling platform was studied. The time domain response of the system was analyzed by building a simplified mathematical model. The offshore hydraulic system was modeled based on AMESim, which offered an effective method to analyze its dynamic characteristics through the system response curves under different parameters, such as pipes length,diameter and oils viscosity,elasticity modulus. The effect of the accumulators position to the system dynamics was also analyzed. The impact of every single factor on system dynamic performance was analyzed based on RSM and the system was optimized. The optimized results improve the response time 349% of the original design. It can be used as reference in future design of offshore hydraulic system with long pipe.
