| 摘 要： | 通过采用有限元法求解船舶下水过程中的墩木反力变化过程,进而得出浮船坞压载水调节方案。为了进一步检验该模型的可靠性,根据计算模型编写计算程序对50000吨级散货船的水平纵向浮船坞下水过程进行计算模拟,实际结果表明该模型能满足船舶水平纵向浮船坞下水受力分析的精度要求。

| Abstract: | The changing process of the reaction of launching block during the ship launching is calculated by the finite element method.Furthermore,the ballast water regulation solution of the floating dock is gained.In order to test the reliability of the mode,a calculation program is designed to simulate the launching process of a 50000 dwt bulk carrier on the level longitudinal floating dock.The result shows that the mode can meet the accuracy requirements of the force analysis during the launching on the level longitudinal floating dock. |

| Keywords: | launching of level longitudinal floating dock reaction of launching block ballast water regulation finite element method |
