Dataset in support of the paper 'Experimental dataset on aluminium wedge slamming: measurements of acceleration, pressure, strain, and video data'

Description

This dataset presents the measurements from three experimental campaigns conducted on a three-dimensional non-prismatic aluminium wedge, complementing the original research article "Slamming loads and responses on a non-prismatic stiffened aluminium wedge: Part I. Experimental study." The experiments were designed to investigate the effects of slamming loads on structural responses through a series of free-fall drop tests. These tests included both symmetric and asymmetric impacts on an aluminium wedge section, designed with two different bottom plates (stiffened and unstiffened) to examine the influence of flexural rigidity on hydroelastic slamming. Vertical acceleration during the free-fall impact was measured using three accelerometers. Sixteen pressure sensors were employed to capture slamming pressures during impact, and twenty strain gauges recorded structural responses in both longitudinal and transverse directions on the wedge surface. Detailed descriptions of the experimental conditions, including wedge geometry, material properties, and the test plan, are provided. The measurements are presented as time histories of sensor records. Symmetric impact tests were conducted at various drop heights ranging from 25 cm to 200 cm and involved two different wedge masses (denoted as m1 and m2) to assess the effect of structural mass on impact-induced loads and responses. Asymmetric impact tests were carried out at three drop heights with heel angles ranging from 5 to 25 degrees. Video footage from different runs is included in this dataset, providing illustrative samples of the experimental procedures.
