An investigation was performed to measure sloshing motion and damping during harmonic forced vertical motion of a rectangular tank containing fluid, with a particular focus on the amplitude dependent transition between lateral sloshing and turbulent, vertical slamming. Qualitative and quantitative explanations are provided for the damping saturation point and dissipation effects, together with metrics to distinguish the different sloshing regimes, and a ballistic-harmonic analytical model is presented capable of reproducing the physical trends. Image processing tools were used to analyse experimental high-speed video footage, illustrating potential routes to increased damping in vertically oscillating structures, and correlating well with measured fluid forces and flow regimes.

进行了一项研究，以测量装有流体的矩形罐在谐波受迫垂直运动期间的晃动运动和阻尼，特别关注横向晃动和湍流垂直砰击之间的幅度相关过渡。提供了阻尼饱和点和耗散效应的定性和定量解释，以及区分不同晃荡状态的指标，并提出了能够再现物理趋势的弹道谐波分析模型。图像处理工具用于分析实验性高速视频片段，说明在垂直振荡结构中增加阻尼的潜在途径，并与测量的流体力和流态相关联。
