摘要
对某集装箱船双层舷侧结构的碰撞历程进行了数值模拟 ,在采用刚性撞头的情况下研究了它的能量吸收能力和碰撞损伤情况 ,并对各个构件在碰撞过程中的作用进行了分析。数值模拟是用大型非线性动态响应分析程序MSC/DYTRAN来完成的。
Described the simulation of the behavior of the double skinned side structure in collision. Assuming the simplified rigid bow of a striking ship, the energy absorption capacity and resulting damage of side structure for a container ship were studied. The contribution of each structure component was also investigated in detail. The simulation was carried out by using MSC/DYTRAN, a three dimensinal analysis code for analyzing the dynamic ,nonlinear behavior of structures.
