| Abstract: | This paper presents the theory and method of analyzing horizontal-torsion-coupled dynamic behavior of a ship hull with large hatch opening by the transfer matrix method. The ship hull is simplified as a free-free nonuniform thin-walled beam. Based on Timoshenko's beam theory and the effects of shear deformation, rotatory inertia and warping torsion, the field transfer matrices of open and close section thin-walled segments are derived. Between different beam segments, the suitable compatibility conditions are made and point transfer matrices are given. The SHTCRP PRG is worked out based on the method derived from this paper and the dynamic behavior of the ship hull with a large hatch opening and three types of beams are calculated. The results show that the theory presented in this paper is reliable and the PRG is of important value in engineering. |
