The present study concerns the stern slamming load of container carriers, with stern bulb arrangement variation. First, a series of wedge drop tests were conducted using simple wedge models with fixed deadrise angles, and tests with the cross-section models of practical container carrier sterns were followed. The deadrise angle of the simple wedge ranged from 0° to 10°. The pressure measurement results of the simple wedge drop tests were distributed between empirical formula and analytic solution, so the experimental setup was validated. In the cases of practical hull cross-sections, the water entry of the bulb prior to that of the transom resulted in characteristic water film generation and delayed pressure peak appearance. The trapped air between the bulbs damped the pressure in the twin skeg hull case, reducing the pressure peak and causing the pressure oscillation during water entry.

本研究涉及集装箱船的船尾撞击载荷，船尾灯泡布置变化。首先，使用具有固定死角的简单楔形模型进行了一系列楔形下降试验，然后采用了实用的集装箱船尾的横截面模型进行了试验。简单楔形的死角范围为0°至10°。简单楔形下降试验的压力测量结果分布在经验公式和解析解之间，因此验证了实验设置。在实际船体横截面的情况下，灯泡的水进入比横梁的水进入要先产生特征性的水膜生成并延迟压力峰值出现。灯泡之间截留的空气减弱了双壳船壳中的压力，
