Abstract In this study, a series of model tests was conducted to investigate the characteristics of wave impact loads and the associated air bubble effects on a vertical circular cylinder with various pressure and force sensors installed in a 2D wave flume. Spilling and plunging waves, generated by the focusing wave method, induced wave impact loads on the cylinder, and these loads were measured by the sensors, which had different natural frequencies and sensing areas. Each test condition was repeated 20 times to verify the repeatability of the impact loads and their effects. The air bubble effects were investigated by analyzing the time histories of the impact forces and pressures, and the effects were related to the natural frequency and sensing area of the sensors. The air bubble effects were observed to increase as the breaking wave developed more at the position of the cylinder. The generated waves and impact loads were also observed to change significantly when even a small noise occurred in the displacement of the wavemaker.

破浪作用下垂直圆柱波浪冲击载荷特性的试验研究

摘要 在这项研究中，进行了一系列模型试验，以研究波浪冲击载荷的特性和相关气泡对安装在二维波浪槽中的各种压力和力传感器的垂直圆柱体的影响。聚焦波法产生的溢出波和突入波在圆柱体上产生波浪冲击载荷，这些载荷由具有不同固有频率和感应面积的传感器测量。每个测试条件重复 20 次，以验证冲击载荷及其影响的可重复性。通过分析冲击力和压力的时间历程来研究气泡效应，其效应与传感器的固有频率和传感面积有关。观察到气泡效应随着破碎波在圆柱体位置发展得更多而增加。即使在造波器的位移中出现很小的噪音，也观察到产生的波浪和冲击载荷发生显着变化。
