运用有限元的方法对深海采矿系统中的扬矿管进行了静力分析和动态分析，将５０００ｍ扬矿管等分成２０个两节点梁单元，应用等效线性化方法及结构对地震的反应原理建立了扬矿管纵向运动模型．采用ＡＤＩＮＡ有限元分析软件．通过研究在海水中不同海浪周期下扬矿管的振动特性可知：扬矿管的一阶纵向共振周期处于海洋中海浪通常出现的周期范围内；共振时扬矿管顶端与末端的纵向振动的相位差接近１８０°，产生轴向应力很大，给管子的设计和操作带来极大的影响．
The finite element method is used to carry on the static analysis and the dynamic analysis of the lifting pipe in the deep sea mining system. The 5000m pipe is equally divided into 20 two-node beam elements. The equivalent linearization method and the response principle of the structure to the earthquake Established vertical pipe lifting model. ADINA finite element analysis software. By studying the vibration characteristics of the pipe at different wave periods in seawater, it can be seen that the first-order longitudinal resonance period of the pipe is within the range of the period in which the ocean waves usually appear in the ocean. When the vibration is between the top and the end of the pipe, Close to 180 ° difference, resulting in a large axial stress, to the pipe design and operation have a tremendous impact.
