The occurrence of parametric resonance due to the time varying behavior of ocean waves could lead to catastrophic damages to offshore structures. A stable structure that could withstand the wave perturbations is quintessential to operate in such a harsh environment. In this work, the authors detail the relevance of a Suction Stabilized Float (SSF) or a Suction Stabilized Floating platform towards such an application. A generic design of a symmetrically shaped float structure along with its inherent stabilization behavior is discussed. Furthermore, the authors extend their prior research on this topic towards modelling the dynamics of SSF and perform stability analysis. The authors demonstrate the dynamical characteristics of SSF analytically using Floquet theory and Normal Forms technique, in this work. Additionally, the simulation results are verified and validated with the numerical methods.

吸力稳定浮动平台的动力分析

由于海浪的时变行为而导致的参数共振的发生可能导致对海上结构的灾难性破坏。能够承受波扰动的稳定结构对于在如此恶劣的环境中运行至关重要。在这项工作中,作者详细介绍了吸力稳定浮标(SSF)或吸力稳定浮标平台与此类应用的相关性。讨论了对称形状的浮子结构的通用设计及其固有的稳定性能。此外,作者将关于该主题的先前研究扩展到对SSF动力学进行建模并进行稳定性分析。在这项工作中,作者使用Floquet理论和法线形式技术分析性地证明了SSF的动力学特性。另外,
