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
其主要內容如下： 1 ）通過薄壁梁理論求得結構參數后，採用遷移矩陣法，在考慮剪切效應、轉動慣量和翹曲影響下，推導出求解破損船體結構的動態特性公式系統的場遷移矩陣和點遷移矩陣，並著重分析了船體不同破損程度和翹曲變形對船體振動的動態特性的影響。 -
At the point of co = g > c, it is the hopf bifurcation that the rotor orbit of shaft centerline is the periodic whirl of small amplitude. the method is suitable for the multi - freedom system
數值求解系統動力學方程，在_ c處，轉子軸心軌跡為極小幅值的周期渦動，此為hopf分岔，分叉后，系統運動為擬周期運動。
