摘　　要：深海采矿船与扬矿管系统的耦合动力分析对采矿系统的研发应用具有重要意义。为了研究波浪引起的扬矿管和采矿船之间的耦合动力响应,采用等效截断设计原则,对扬矿管截断模型的弹性模量、轴向刚度以及单位长度质量等特征参数进行优选,得到了合理的截断模型参数。基于相似理论建立了深海采矿5000 m扬矿管耦合动力学试验模型,解决了深海采矿系统在有限水深试验条件下进行模型试验的问题。同时开展了不同波高、不同波向角和不同矿仓质量下采矿系统模型的耦合运动试验,结果表明,波高、波向角和矿仓质量对耦合响应的幅值、耦合作用时间均有较大影响。该试验模型的建立,为后续管道稳定性和升沉补偿特性的研究提供了技术基础。The coupling dynamic analysis of deep-sea mining vessel and lifting pipe system has a great significance to the research and application of mining system.In order to research the coupling dynamic response between the mining vessel and lifting pipe caused by waves,the characteristic parameters of the truncation model of lifting pipe were optimized by the equivalent truncation design principle so as to obtain the reasonable truncation model parameters,including elastic modulus,axial stiffness and mass per unit length.Based on the similarity theory,a coupling dynamic test model of 5000 m lifting pipe in deep-sea mining was established,which solved the problem of model test of deep-sea mining system under the condition of limited test water depth.Meanwhile,the coupling motion experiments of deep-sea mining system model under different wave heights,wave direction angles and buffer masses were carried out.The results show that wave height,wave direction angle and buffer mass have great influences on the amplitude of coupling response and the coupling time.The test model provides a technical basis for the subsequent study of pipeline stability and heave compensation characteristics.
