Abstract
This paper reviews a study on the nonlinear dynamics of a super-scale floating airport that consists of multiple floating modules with a flexible connection system. A novel network structure dynamics method is proposed for the dynamics prediction of the floating structure. A network modeling method is developed for the super-scale floating airport with arbitrary topological configuration and connection and the experimental validation is conducted in a wave basin. Nonlinear dynamics and network synergetic effect of the floating airport are elaborated, especially for the physical phenomenon of “amplitude death” that plays a key role in the system stability. The mechanism for the occurrence of amplitude death (AD) in non-autonomous systems is revealed and further the mathematical criterion is derived. The stability analysis based on amplitude death mechanism is carried out. Some applications of the network structure dynamics method in ocean engineering is illustrated. Finally, the prospective of the methodology is addressed, potentially extendable to many engineering problems with network structure alike.
