| 摘 要： | 本文提出三谐调至五谐调主船体垂向和水平方向振动的固有频率估算的几个新公 式．这些公式是以实船激振试验时获得的固有频率为基础，采用线性回归的方法推导 出来的。这些公式特别适用于船舶设计的初始阶段。它不仅可用于普通强度钢材料建 造的船舶．而且也适用于中部区域内的主要构件采用高强度钢材料建造的船舶．

| Abstract: | This paper presents several new approximate formulae for computing the natural frequencies of 3 to 5 modes of vertical and horizontal vibration of ship hull. These formulae are based on the measured frequencies of several similar ships. They can be used especially in the primary step of ship design as well as in the main ship construction where the material of normal strongth steel or higher tensile steel is used. |
