摘要
输流管道的振动问题是当前学术界研究的一个热点,数学建模是解决问题的关键。当前一些文献中给出的方程错误很多,物理背景也不清楚。文章修正了诸多错误,并按地上线性管道、地上非线性管道和埋地管道重新进行了分类,给出了最常用的管道振动微分方程。
The study of vibration problems of fluid-conveying pipes is a hotspot of academia, and Math modeling is the key to solve the problem. Some wrong equations were given by documents currently and their physical backgrounds were not clear. So the correction was carried out and the models were classified as linear overground pipes, nonlinear overground pipes and buried pipes, respectively. At last, the most universal equations were introduced in this paper.
