摘要
针对舰载方舱侧壁结构的设计任务,进行设计需求分析,明确影响侧壁结构设计的主要因素。将方舱等效为上层建筑,采用规范计算得到侧壁设计载荷;对比分析加筋板和波纹板2种结构型式的结构强度、刚度、固有频率等方面的差异;对波纹板型式,探讨波纹深度、波纹面板宽度,以及腹板与面板夹角等参数对结构性能的影响。结果表明,在相同重量下,波纹板的结构性能较加筋板优;波纹板相关参数的选取应权衡多方面因素来考虑。
The design of the sidewall structure of the shipboard shelter was investigated.The design requirements and the main factors affecting of the shipboard shelter were clarified.Based on the concept of equivalent superstructure,the load acting upon the sidewall was calculated in terms of rules.The difference of the strength,stiffness and natural frequency for the stiffened plate and corrugated plate were compared.For corrugated plate,the effects of parameters such as the corrugated depth,corrugated width and the angle between the web and panel of the structure performance were discussed.The results showed that under the same weight,the structural behavior of corrugated plate is better than that of stiffened plate,and the relevant parameters of corrugated plate should be taken into account in many aspects.
