摘　　要：The development of very large floating structures(VLFSs)through the integration of multiple modules linked by connectors has resulted in a sophisticated multi-oscillator system.These flexible connectors are crucial to the stability and safety of the entire system,as they accommodate the dynamic interactions between the modules.The versatility of such complex configuration platforms,enhanced by multi-directional connectors,allows for a wide range of engineering applications owing to their adaptability in assembly and arrangement.In this study,a dynamic model within the frequency domain is meticulously constructed by linear wave and dynamic theories.This model facilitates a detailed hydrodynamic response analysis of complex configuration platforms,specifically those composed of triangular modules.The introduction of power flow theory further elucidates the coupling mechanisms and energy transmission effects within multi-directional connectors,offering valuable insights for the preliminary design layout of these platforms.Moreover,the research delves into the optimization of the stiffness configuration of the connectors.An optimization model is established via the linear weighted sum method,which considers the motion responses of the modules and the loads borne by the connectors.The genetic algorithm(GA)is employed to refine the stiffness configuration of the connectors with three-directional layout.This comprehensive approach not only enhances the understanding of the hydrodynamic behavior of VLFSs but also provides a methodological framework for optimizing their structural design.These findings are expected to significantly contribute to the field of marine engineering and inform the development of more robust and efficient VLFSs for various applications.
