摘要

摘要: 海上浮动机场由多个浮体模块柔性连接组成, 是一个典型的刚柔流耦合的多振子网络系统. 从网络动力学角度提出一个新的建模方法, 构建了具有链式拓扑结构特征的海上浮动机场非线性力学模型. 数值仿真分析了浮动机场的非线性响应和连接件载荷, 表明线性分析方法可能严重低估了实际情况. 探讨了浮体模块响应的网络协同效应, 以及"振幅死亡" 现象. 初步探讨了振幅死亡与连接件刚度参数和波浪周期的关系, 对海上浮动机场的稳定性设计具有特殊意义. 为研究非线性网络结构动力学问题, 包括大型海上浮体结构, 提供一个新的分析工具和应用范例.

Abstract: Floating airport consisting of multiple flexibly connected modules is a typical dynamic network with flexiblerigid- fluid coupling. A new method is proposed for modeling and a chain-topological network model for the floating airport is developed. In numerical simulations, the nonlinear responses of surge, heave, pitch motions and loads of connectors are analyzed implying that the classical linearization approach may severely underestimates the actual results. Further, this paper studies synergetic dynamics of the network and amplitude death phenomena. The onset of amplitude death associated with coupling stiffness and wave period are illustrated, which is important for the stability safety design of the floating airport. This work provides a new methodology and an application example in the study for network structural dynamics, including very large scale floating structures.
