本文研究了对填充液体的容器的包装过程中发生的液体晃动进行建模的问题。晃动效应是由一维间歇运动引起的，由于质量控制过程（例如称重）的必要性，晃动效应是不受欢迎的。因此，通常应用运动优化来最大程度地减少残余振动。为此需要有效的流程模型。本文的目的是推导出用于描述不同运动和常见实际情况（例如不同容器几何形状以及机器运行速度）的液体晃动行为的模型，并说明模型的使用限制。讨论了已知的模型方法，并通过实验审查了它们的假设。这导致了一组有限的运行速度范围，其中应用模型的假设是有效的。这些模型是根据实验数据推导出来的，并进行比较，从而确定模型在运行速度依赖性方面的有效性。最后，通过比较不同运动曲线描述振动的预测效率，研究了推导模型的有效性。
The present paper deals with the problem of modeling liquid slosh occurring in the packaging process of containers filled with liquid. Sloshing effects are induced by one-dimensional intermittent motions and are undesired due to the necessity of quality control processes, such as weighing. Therefore, motion optimizations are often applied with the intention to minimize the residual vibrations. Valid process models are required to do so. The aim of this paper is to derive models for describing the liquid slosh behavior for different motions and for common practical circumstances, e.g., different container geometries as well as machine operating speeds, and to state the model’s limits of use. Known model approaches are discussed, and their assumptions are reviewed experimentally. This leads to a set of limited ranges of operating speeds in which the applied models’ assumptions are valid. The models are derived for these sets from experimental data, and a comparison is executed that enables the determination of the models’ validity concerning their operating speed dependency. Finally, the validity of the derived models is investigated by comparing their predictive efficiency of describing the vibration for different motion profiles.
