| 摘 要： | 为了研究舰船甲板的变形,对其结构进行了简化,建立了舰船甲板受力的数学模型。分别在横向载荷、总纵弯矩及二者共同作用等3种情形下,对舰船甲板的变形特性进行了计算。计算结果表明,舰船甲板受力变形为mm级;在横向载荷作用下,舰首甲板变形最大;在总纵弯矩作用下,甲板的0.6~0.75间部位变形最大。

| Abstract: | The structure of deck was simplified to analyze the deck deformation. Then the mathematic model of deck under forces was developed. The deck deformation was numerically analyzed under the influence of transverse load, longitudinal bending moment and both of them. The results show that the deck deformation is millimeter grade. The transverse load can result in maximum deformation in the bow deck. The deck between the 0.6 -0.8 longth has maximum deformation under longitudinal bending moment. |
