| 摘 要： | 文章采用动力学方法,利用LS-DYNA的流固耦合功能,考虑了船舶下水的惯性力、水动力以及船体水下形状等因素,对船舶下水过程进行了三维有限元数值模拟。与传统静力学方法比较,动力学方法不仅能够准确的预报船舶在下水过程中的受力情况,而且能够得到船舶下水过程中瞬时速度、加速度及浮态,能够适应现代造船质量控制的要求。

| Abstract: | In the paper,the dynamic analysis method and the three-dimensional finite element method have been used to calculate launching ship＇s dynamic motions based on fluid-structure interaction of LS-DYNA.In addition,inertia force,hydrodynamic force and the shape of the ship have been referred.The force of a launching ship could be got,as well as speed,acceleration and floating condition.The results of this numerical method and the traditional statics method have been compared and analyzed. |
