深海采矿系统中，扬矿管纵向振动是影响扬矿管寿命的主要因素。本文对带有泵组及中间仓的阶梯式扬矿管的纵向振动进行了建模，并用解析方法对方程进行求解，通过计算机的模拟计算，分析了扬矿管纵向振动稳态响应的特性。
In the deep-sea mining system, the longitudinal vibration of the pipe is the main factor that affects the life of the pipe. In this paper, the longitudinal vibration of stepped pipe with pumping unit and intermediate tank is modeled, and the equation is solved by analytic method. The characteristics of the longitudinal response of the pipe are analyzed by computer simulation.
