摘　　要：运用非线性有限元方法对深海采矿扬矿管的横向运动特性进行了研究 ;对影响扬矿管横向变形和动态应力的各种因素作出详细的分析 ,提出了“位移滞后期”的概念 。Dynamic analysis for the lateral movement of a lifting pipe in deep sea mining is made by using nonlinear finite element method. The factors influencing the dynamic stress and deformation of the lifting pipe are analyzed in detail by means of ADINA. A new concept of ‘displacement delaying time’ is put forward and related influencing factors are also discussed. The results obtained are of great importance to the design and operation of the lifting pipe. [
