摘要
全面分析了船舶碰撞后的运动形式,提出了一种模拟最危险船舶碰撞时的计算模型,并对计算模型进行了刚塑性动力分析。此方法不仅考虑了船侧结构对碰撞结果的影响,而且考虑了船舶速度及船舶尺寸对船舶碰撞的影响。同时模拟碰撞的情况进行了模型试验,并将模型试验的结果与计算方法进行了比较。
Based on analysing the motion states of ships in collision,this paper advances a calculation model for most critical ship collisions and conducts rigid-plastic dynamic analysis of the model. The paper considers not only the effect of the side structure of ships on the collision results but also the yeffect of ships' speed and sizes on collision. Finally, tests are made to validate the above abalysis.
