The major work is as follows : 1 ) based on dry hull modal analysis of flexure - torsion coupling vibration of unsymmetrical ship structures about longitudinal centerline , a transfer matrix method to calculate the dynamic characteristics is adopted after the parameters of structures are specified . taken both shear effect and warping deformations into account , the point and field transfer matrices are derived , and the influence on dynamic characteristics is computed according to different damaged positions and areas
其主要内容如下： 1 )通过薄壁梁理论求得结构参数后，采用迁移矩阵法，在考虑剪切效应、转动惯量和翘曲影响下，推导出求解破损船体结构的动态特性公式系统的场迁移矩阵和点迁移矩阵，并着重分析了船体不同破损程度和翘曲变形对船体振动的动态特性的影响。
