This invention discloses a method for evaluating the hydrodynamic response of flexible floating structures considering the equivalent effect of impermeable upper water. First, a three-dimensional hydroelastic-porous sidewall coupled model is established, equating the flexible structure to an elastic disk below the still water surface, with the outer impermeable boundary equivalent to a porous sidewall with minimal permeability. By dividing the external water area, the internal confined overlying water layer, and the lower water body and defining velocity potentials, semi-analytical solutions for the velocity potentials of each region are constructed using the separation of variables method and the eigenfunction expansion method. Combining fluid continuity conditions and porous sidewall matching conditions with pressure jump compensation, watershed matching is performed to solve for each modal coefficient, and then wave excitation force, deflection response, and free surface response are calculated. This invention, through layered modeling and near-impermeable boundary equivalence treatment, evaluates the water-blocking effect of the solid floating ring and the influence of the confined overlying water layer on the hydrodynamic response of the flexible structure, providing a theoretical basis for the structural optimization and wave-resistant design of floating photovoltaic systems under impermeable upper water conditions.
