摘要:

在拖曳水池对某集装箱船进行了砰击模型试验.在船底砰击的脉冲三角函数形式的基础上结合试验数据重新确认外张砰击持续时间,建立了一种外张砰击压力时间分布的模型.并且基于瓦格纳型冲击理论对该船的外张砰击压力时历进行预报.预报和试验结果的比较表明,两者吻合较好,该方法能适当反映外张砰击的时历特性.

Abstract:

Slamming ship model experiments of a container ship were conducted in the wave basin. Based on the form of impulse triangle of bottom slamming and experimental data, the time of flare slamming was obtained again, and the time distribution model of flare slamming was established. Besides, the flare slamming pressure of this ship was predicted by Wagner’s theory of impact. The experimental results showed that the theoretical results were in a good agreement with the experimental data and the flare slamming time characteristic was reflected by the method properly.
