Abstract

A new method for non-intrusive surface load measurement during water wave impact is introduced. The wave impact on a thin steel plate was measured using a deflectometry setup for full-field optical deformation measurements. Surface pressure distributions were reconstructed by applying the global equilibrium equation using the virtual fields method (VFM), enabling full-field and time-resolved information. This approach represents a promising advancement over the conventional point-wise or sub-area measurements that are typically conducted with transducers and load cells. The practical application of this method was demonstrated during an experimental campaign at the SINTEF towing tank facility. The test campaign successfully captured full-field, time resolved deformation data from wave impacts on the investigated flat steel plate specimen. Pressure and forces were reconstructed using the VFM and compared to force panel measurements. The current study shows that this load reconstruction method can provide accurate, time-resolved loading information with a high density of data points. Additionally, the method’s high spatial resolution and sensitivity helped to identify various spatial characteristics of the water wave impact.

水波冲击现场压力重建研究进展

介绍了一种非侵入式水波冲击表面载荷测量新方法。用偏转计装置测量了波对薄钢板的影响，该装置用于全场光学变形测量。利用虚拟场法（VFM）应用全局平衡方程重构地表压力分布，实现全场和时间分辨信息。与传统的点或分区域测量相比，这种方法代表了一种有希望的进步，这些测量通常是用传感器和称重传感器进行的。该方法的实际应用在SINTEF拖曳罐设施的实验活动中得到了验证。测试活动成功地捕获了受测钢板试件上波浪冲击的全场、时间分辨变形数据。使用VFM重建压力和力，并与力面板测量结果进行比较。目前的研究表明，这种载荷重建方法可以提供准确的、时间分辨的载荷信息和高密度的数据点。此外，该方法具有较高的空间分辨率和灵敏度，有助于识别水波冲击的各种空间特征。

期刊介绍： The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
