| 摘 要： | 将扬矿管考虑成弹性梁，通过分析梁单元在垂直平面所受的各种横向载荷的影响，建立梁单元横向振动的数学模型，同时根据扬矿管的边界条件，利用伽疗金法，对运动方程进行求解。求出扬矿管相对于船的偏移、扬矿管的弯曲应力以及在不同拖航速度及不同时刻扬矿管的偏移和弯曲应力的变化规律，给扬矿管的整体设计提供依据。

| Abstract: | The deep sea mining pipe is considered as elastic beam, the mathematics model of lateral vibration of beam element for different lateral loads on the vertical beam is built The model is calculated numerically by the Galerkin method and the boundary conditions of the pipe The relative displacement of the pipe to the ship, the bending stress of the pipe, and their changes are evaluated These results can be applied to the design of pipe string |
