对于过去文章中提出的从5000m和6000m深的海底开采锰结核的2种扬矿管模型，分别完成了时域内垂直状态下轴向强迫振动和三维拖曳特性的非线性动态分析。所用的海底采矿分析方法以集中质量法和增量迭代法为基础。用纽马克（Newmark）方法进行时间积分。水中的泵及缓冲器看作刚体。基于模拟分析，对扬矿管设计的两个问题进行了讨论：管的结构强度和采矿作业的总体集中控制。
In the past article, two kinds of pipe models for mining manganese nodules from the seafloor of 5000m and 6000m are proposed, and the nonlinear dynamic analysis of axial forced vibration and three-dimensional towing behavior in the vertical state are completed respectively. The seabed mining analysis method used is based on the mass-quality method and the incremental iteration method. Use the Newmark method for time integration. Water pump and buffer as rigid body. Based on the simulation analysis, two issues of pipe design were discussed: the structural strength of the pipe and the overall centralized control of mining operations.
