深海采矿扬矿硬管纵向振动的解析分析

Theoretical Analysis of Longitudinal Vibration of Mining Pipe in Deep Ocean

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。

Longitudinal Vibration of a mining pipe is a key factor effecting the longevity of a mining pipe designed for mining maganese nodules in the deep ocean.the paper builds the mathemetical model of longitudinal vibration of a ladder pipe with two pumps and buffer bin,and solves the equation by use of theoretical method. Simulated by computer,the character of steady-state responses of the pipe was analyzed.
