摘要
笔者在国内首次利用非线性显式有限元方法对可变形的船首结构撞击可变形的船侧结构的全过程进行了动态模拟。本文通过对一艘 4 0 0 0 0t油船正撞 30 0 0 0t散货船船侧的数值仿真讨论了船舶碰撞数值仿真中所涉及的关键技术 ,给出了船舶碰撞仿真中提高计算效率、精确性和稳定性的原则和方法。
The numerical dynamic simulation of the deformable striking ship bow colliding the deformable struck ship side structure is performed by non linear explicit finite element method. Through the example of a 40000 DWT oil tanker colliding a 30000 DWT bulk cargo ship, the key technique of simulation of ship ship collision is discussed in the paper. Some practical ways in improving computing efficiency, accuracy and stability for collision simulations are given.
