碩士 === 國立臺灣海洋大學 === 河海工程學系 === 99 === A numerical model was developed through usage of dual boundary element method to investigate the responses of a two-dimensional floating structure with flexible skirts.Theoretical conception is on basis of potential theory with linear external forces,and the equation of motion of the flexible skirts is taken to be that of a beam of uniform flexural rigidity and mass per unit length subjected to a constant axial force,and motion of skirts are assumed to be small and linear .the dynamic behavior of the flexible skirts is described through an appropriate Green function. Numerical results are presented which illustrate the agreement between flexible skirts and rigid skirts results was reasonable,and illustrate the motion of the floating body effect caused flexible skirts,and the motions of skirts is the most dramatic movement with Young’s modulus and skirts length varies.
