【摘要】：近海结构的研究是海洋工程领域的重要专题。本文以Airy线性波理论和莫里森方程为基础推导平台结构的运动方程。将波浪力简化为二节点集中载荷,从动力学的角度分析结构的响应特征。以一简化的固定平台为算例,以不同的入射波为激励条件分析比较结构的位移响应、速度响应以及加速度响应。研究结果表明,随着入射波强度的增大,结构的振动变得更为剧烈,且结构的振动响应不仅与入射波的周期和波高有关,与波浪的形式也有一定的关系。
[Abstract]:The study of offshore structures is an important topic in the field of ocean engineering. Based on Airy's linear wave theory and Morrison equation, the motion equations of platform structures are derived in this paper. The wave forces are simplified as two-node concentrated loads. The response characteristics of the structure are analyzed from the dynamic point of view. Taking a simplified fixed platform as an example, the displacement response, velocity response and acceleration response of the structure are analyzed and compared with different incident waves. The results show that, With the increase of incident wave intensity, the vibration of the structure becomes more intense, and the vibration response of the structure is not only related to the period and height of the incident wave, but also to the form of the wave.
