摘要
提出了船舶气囊下水的动力学分析方法,建立了气囊下水的动力学方程,采用四阶龙格-库塔方法来求解运动方程,并编制了相关程序进行计算。将计算结果与多次实船下水的测量结果进行比较,得出计算结果符合下水的实际情况,表明分析模型和方法具有较好的精度。
This article presents the hydrodynamic analyze method of ship launching with air-bag.The hydrodynamic equation was established and solved by fourth order Runge-Kutta method.The comparison between calculation and measured results of multiple ship launching with air-bag shows that the hydrodynamic analyze method and the equation described are reasonable.
