摘　　要：建立了深海采矿扬矿管的纵向振动微分方程,应用矩阵迭代法求取扬矿管的固有频率和固有振型,使用MAT-LAB得到了扬矿管固有频率,并绘制扬矿管的固有振型曲线。采用直接积分法中的Newmark法求解扬矿管的动力学响应,利用abaqus对扬矿管的纵向振动进行了仿真计算,绘制了扬矿管上4个位置的振动随时间的变化曲线,以及在10个采样时间点扬矿管振动随位置的变化曲线。The differential equation of longitudinal vibration of the lifting pipe in deep-sea mining was established.The natural frequency and natural array of the lifting pipe were obtained by matrix iteration method.The natural frequency of the lifting pipe was obtained by using MATLAB,and the natural array curve of the lifting pipe was drawn.The dynamic response of lifting pipe was solved by Newmark method of direct integral method,and the longitudinal vibration of lifting pipe was simulated by abaqus.The time-varying curves of vibration at five positions on lifting pipe were drawn,as well as the position-varying curves of vibration on lifting pipe at 10 sampling time points.
