| 摘 要： | 甲板纵骨的稳定性问题是水面舰船结构设计中的一个重要问题。《舰船通用规范》和《水面舰艇结构设计计算方法》对纵骨带板折减系数取法的差异有时会导致工程中出现不同的结果。从理论上分析了《舰船通用规范》和《水面舰艇结构设计计算方法》对纵骨屈曲分析评估方法的差异,并用数值算例结果给予说明。研究结果为:《舰船通用规范》中的稳定性校核标准较《水面舰艇结构设计计算方法》严格,对于理解和修订国军标以及保证舰船结构安全有一定的理论意义和实用价值。

| Abstract: | Deck longitudinal stability problem is an important issue for surface warship’s structure design.Different methods in determining the longitudinal band plate reduction coefficient according to the standard of Ship General Specifications(SGS,GJB4000-2000) and Structure Design and Calculation Method for Surface Ship(SDCM,GJB/Z119-99) maybe lead to different conclusions.Differences between these two national military standards were analyzed by theory and explained by numerical computation examples.Results show that the standard of SGS is more strict than SDCM. |
