| 摘 要： | 某些船舶,因作业需要,对其船体的姿态角(刚体的纵摇角 弹性体变形的转角)提出了预报的要求,本文以船体纵向角位移为例,采用二维船体梁模态叠加方法和最大熵原理估算船体在随机波激励下纵向变形转角的响应特征值,并以某快速船为例,估算该船的纵向变形转角,供设计使用者参考,其计算的思路也可应用于其它方向的变形转角估算。

| Abstract: | The prediction of some ships' longitudinal attitudes(rigid pitch angular deflection) is needed for its operation in random wave.In this paper,a fast ship as an example is taken and the statistical characteristic value of deflect angular girder in random waves is estimated by some methods of ship hydroelasticity and the principle of maximum entropy.The results can be provide to designers and cusformers for use,and the method can also applied in the deflection estimation of other freedom. |

| Keywords: | Ship's attitude deflect slope random waves responding characteristic value |
