摘要
各种输液管道(包括埋地管道)的振动问题是当前学术界研究的一个热点,而数学建模又是解决问题的关键。将土约束简化为均布非线性弹簧、线性弹簧,推导出了埋地管道的平面外振动微分方程及扭曲运动的微分方程。
The study of vibration problems of different fluid-conveying （included pipes buried fluid-conve- ying pipes） are a hotspot of present academia, and math modeling is the key to solve the problem. The soil was separately hold to look upon nonlinear spring, linear spring and uniform load in the text, derived the oscillatory differential equation of vertical plane and torsional vibration of buried fluid-conveying pipes.
