Experimental data for the fluid-structure interaction between a double pendulum with a friction hinge and focused waves

This is a dataset from an experiment conducted in the small towing tank of the Ship Hydromechanics Laboratory of Delft University of Technology. The internal project number is 202011. The project leader is Peter Wellens ([e-mail]).<br>A double pendulum with a friction hinge as the bottom hinge was subjected to a focused wave. Three different lengths of the pendulum were investigated and three different values for the focus location of the wave were adopted.<br>The wave height at three locations, both angles of the pendulum, accelerations of both parts of the pendulum and the torque in the bottom hinge of the pendulum were measured. Videos were taken from the focused wave impacting on the bottom part of the pendulum. Photos and videos can be found in Photos.rar and Videos.rar.<br>The main intention of the experiment was to investigate the influence of plasticity on the behaviour of the pendulum.

本数据集源自代尔夫特理工大学船舶流体力学实验室小型拖曳水池开展的一项实验，内部项目编号为202011，项目负责人为Peter Wellens（电子邮箱：[e-mail]）。
本次实验采用底部铰链带有摩擦铰（friction hinge）的复摆（double pendulum），对其施加聚焦波浪（focused wave）。实验共设置三种不同的摆长，以及三种不同的波浪聚焦位置。
实验采集了三处位置的波浪高度、摆体的两个摆角、摆体两部分的加速度，以及摆体底部铰链处的扭矩。同时拍摄了聚焦波浪撞击摆体下部的视频。相关照片与视频可分别从Photos.rar与Videos.rar压缩包中获取。
本实验的核心研究目标为探究塑性效应对复摆运动特性的影响。
