The invention provides a variable-spacing ribbing type transverse half bulkhead and a strength analysis method, the variable-spacing ribbing type transverse half bulkhead is applied to a superstructure of a ro-ro passenger ship, the variable-spacing ribbing type transverse half bulkhead comprises a ribbing type transverse half bulkhead, the ribbing type transverse half bulkhead adopts a ribbing spacing of 0.5 S in an area close to a broadside of the superstructure, and the ribbing type transverse half bulkhead adopts a standard ribbing spacing S in a middle area, the end parts of the ribbing type transverse half bulkheads are connected with supporting columns; the invention has the following beneficial effects: by adopting the structural form of the variable-spacing ribbing type transverse half bulkheads, the problems that a high stress concentration area appears at the end part of the conventional strut under the rolling working condition and deformation and cracks are generated after the high stress concentration area easily appears at the bottom close to the broadside can be effectively solved; in addition, a whole-ship finite element calculation method and semi-analytic analysis software PULS are adopted for conducting strength checking on the structure of the variable-spacing ribbing type transverse half bulkhead, and the structural strength of the ro-ro passenger ship transverse half bulkhead is improved according to the calculation result in combination with function requirements.
本发明提供一种变间距压筋型横向半舱壁及强度分析方法,应用于客滚船的上层建筑,包括压筋型横向半舱壁,所述压筋型横向半舱壁在靠近上层建筑舷侧的区域采用0.5S的压筋间距,所述压筋型横向半舱壁在中间区域采用标准压筋间距S,且所述压筋型横向半舱壁的端部连接有支柱;本发明具有以下有益效果:本发明采用变间距压筋型横向半舱壁的结构形式,可有效消除横摇工况下常规支柱的端部出现高应力集中区的问题和靠近舷侧的底部也容易出现高应力集中区后产生变形和裂纹的问题,还有本发明采用全船有限元计算方法和半解析分析软件PULS对变间距压筋型横向半舱壁的结构进行强度校核,根据计算结果结合功能需求提高客滚船横向半舱壁的结构强度。
