摘要
对可装4 300辆的汽车运输船(PCTC)带浮筒下水过程的动力学采用牛顿第二定律进行计算,对计算方法的选取以及影响计算结果的因素进行分析;计算模块分为下水过程中船舶的状态、运动参数、回转轨迹、全浮时横稳性计算;计算结果与实际下水结果较吻合,计算较准确。
The Newtonian second law is applied to calculate the hydrodyramic characteristics ot the process of the 4 300 cars carrier launching with pontoon. This paper discusses about the computing methods and the factors influencing the numerical results. The computation includes several modules to calculate the ship＇s floating states, the parmneters of movement of launching, the turning track after launching and the transverse stability when floating on ever keel. The numerical results tallied with the real ship launching,
