| 摘 要： | 目前国际上船舶碰撞外部动力学的解析法研究均局限于船体碰撞运动的二维假设,忽略了可能存在的大幅横摇。依据文献1]给出的二维船舶碰撞数学模型,建立了包括横移、纵移、首摇和横摇在内的三维船舶碰撞数学模型,并编制程序对文献2]中的算例进行计算,计算结果表明船舶横摇运动在大多数船舶碰撞情况下是不可忽略的。

| Abstract: | At present,the researches around the world on the external dynamics in ship collision are all restricted to the ship motion in two dimensions,which large scope of roll motion is neglected.After analyzing the two-dimensional ship-ship collision mathematical model presented by Ref.1],a three-dimensional ship-ship collision mathematical model,which includes surge motion,sway motion, yaw motion and roll motion,is suggested in this paper.The calculation result obtained using the present procedure suggested by authors proves that the roll motion in most ship collision scenarios cannot be ignored. |
