摘要

本文旨在对流体运动引起的振动的一种影响进行综述。一般来说,对系统结构的研究影响了构建这些系统的组件的效率。本文通过理论计算、实际试验和数值分析,研究了产生的振动和内部压力对流体输送管道的影响,以确定和测试静态流体输送管道的动态行为。实验研究考虑了各种稳定情况下流体压力效应引起的固有频率。测试了所有液体,如油、水、气体、空气和蒸汽在管道中的流动情况,并正确调整了数学模型。所有的实证、理论、数值和分析研究都一致认为,存在几种方法来开发、修改和改进这些指标。然而,影响流变测量的一个因素是振动,在20世纪中期,由于主要发现损伤可能源于振动,这一问题得到了解决。在此基础上,他们提供了与运动流体的压力和速度测量以及产生或非诱发振动的影响相匹配的数学模型。这项研究表明,迫切需要更多的实证调查,特别是更详细的分析方法,以产生更好的结果。

Flow Induced Vibration for Different Support Pipe and Liquids: A review
This study aims to review flow-induced vibration one of the repercussions of vibrations is caused by fluid movement. In general, the investigation of the structure of the systems affects the efficiency of the components that construct those systems. This review examined the influence of generated vibrations and internal pressure on fluid transport pipes using theoretical calculations, practical tests, and numerical analysis to identify and test the dynamic behavior of static fluid transport pipes. The experimental study considered the natural frequencies caused by the fluid pressure effect under various stability situations. The flow of all liquids, such as oil, water, gas, air, and vapors, through the pipes, was tested, and the mathematical models were correctly adjusted. All empirical, theoretical, numerical, and analytical research agrees that several approaches exist to develop, modify, and improve these metrics. However, one factor affecting rheological measurements is vibration, which was addressed as needed in the middle of the 20th century due to major discoveries that damage could be rooted in vibration. Established on the determinations, they provided mathematical models paired with pressure and velocity measurements of moving fluids and the influence of produced or uninduced vibration. This study demonstrates that additional empirical investigations, particularly more detailed analytical methodologies, are urgently required to produce better findings.
