本文对规则波场作用下驳船内刚性安装的半满液舱内液体的晃动现象进行了数值研究。本文详细介绍了在时间域中发展的数值格式，以研究波浪诱导的驳船运动与部分装满的集装箱中晃动振动的相互作用。采用数值方法得到的晃动时程结果与Nasar等人的实验结果进行了验证。(2008)对液体装填水平(25%、50%和75%)的晃动振荡中的谐波进行了分析。
The sloshing phenomenon of liquid in a partially filled tank mounted rigidly within a barge exposed to regular wave field has been considered for numerical investigation. This paper details the numerical scheme developed in time domain to study the interaction of wave induced barge motion with sloshing oscillations in a partially filled container. The sloshing time history results obtained from the numerical scheme adopted are validated with experimental measurements of Nasar et al. (2008) The harmonics present in the sloshing oscillation for the liquid fill levels (25%, 50% and 75%) have been analyzed.
