Vibration phenomena requiring understanding of fully coupled fluid–structure systems, including fluid-conveying tubes, pipes, and so on, are a dynamic type of problem that have been investigated by numerous authors. The first serious research papers on fluid- conveying tubes, or the pipes vibration phenomena, started to appear in the 1960s, see, for example, Paidoussis.^1,2 The first paper on transient effects of this subject published in the early 1900s was “Theory of Water Hammer” by Allievi.³ Reviews of the research field were published in 1995 by Tijsseling⁴ and in 2009 by Wang and Ni.⁵ As described by Wang and Ni,⁵ the research of flow-induced vibration of slender structures has been intensified during the past few decades. As stated, this is due to the increasing need for stability and reliability in a broad range of industrial applications: applications ranging from nuclear reactors, heat exchangers, ocean mining pipes, and drill strings as described by, for example, Paidoussis,⁶ Xia et al.,⁷ and Zhang et al.⁸ Repeated failures have given evidence to the lack of insight in the physics involved in these types of systems. The phenomena of dynamics related to the internal and or external axial flow fluid–structure interaction (FSI) is a relatively new area of research unlike the case of vibration of slender structures subjected to cross flow. A proposal to address the above type of problem using a fluid-elastic modeling approach is presented. A first effort on applying this method to describe the FSI physics appearing in a high-pressure hydraulic hose system has been made, based on the first author’s past research background, including the development of a so-called generalized aeroelastic methods software described by Hyvärinen.⁹

进行液压软管动力学研究的概念研究，以了解软管的流固耦合行为

需要了解完全耦合的流体结构系统（包括流体输送管，管道等）的振动现象是一种动态类型的问题，许多作者对此进行了研究。关于流体输送管或管道振动现象的第一批严肃研究论文开始于1960年代，例如，见Paidoussis。^1,2 1900年代初发表的有关该主题瞬态效应的第一篇论文是Allievi的“水锤理论”。³该研究领域的评论于1995年由Tijsseling ⁴发表，于2009年由Wang和Ni发表。⁵如Wang和Ni所述⁵在过去的几十年中，细长结构的流致振动研究得到了加强。如前所述，这是由于在广泛的工业应用中对稳定性和可靠性的需求不断增长，这些应用包括：核反应堆，热交换器，海洋采矿管道和钻柱，如Paidoussis，⁶ Xia等所述。等⁷和Zhang等。⁸反复的失败证明了对这类系统所涉及的物理学缺乏洞察力。与内部和/或外部轴向流动的流体-结构相互作用（FSI）有关的动力学现象是一个相对较新的研究领域，与细长结构受横流振动的情况不同。提出了使用流体弹性建模方法解决上述类型问题的建议。基于第一作者的过去研究背景，其中包括开发由Hyvärinen描述的所谓的广义气动弹性方法软件，人们首次尝试使用这种方法来描述出现在高压液压软管系统中的FSI物理现象。⁹
