摘 要: 通过薄壁梁理论和有限元全船结构分析,校核南漳河汽渡驳船的总纵强度,并对结果进行对比分析。薄壁梁理论考虑了最危险的状况,保留了一定的安全系数,对于计算一般的船舶是合适的。有限元全船模型计算总纵强度作为薄壁梁理论一个很好的补充,将成为以后发展的趋势。通过对2种计算方法的讨论,并用图标结合给出计算结果,明确了2种方法各自的优缺点,具有一定的参考价值。
关 键 词: 船舶、舰船工程;薄壁梁理论;有限元;总纵强度

Abstract: Through the thin-walled beam theory and finite element analysis of ship structure, this article checks the car ferry barge longitudinal strength of Nan Zhang river, and analyses the comparison of the results . The theory of the thin-walled beam considers the most dangerous loading status of the ship, and retains a certain safety factor, so it is appropriate for the majority of the ships. Longitudinal strength of ship model calculated by finite element can be as a good complement to thin-walled beam theory, and it will become the development trend in the future. Through the discuss on these two calculation methods and combining with the figure legends, the calculation results are given. In addition, the advantages and disadvantages of these two methods are cleaned, which have a certain reference value.
Key words: ships and warships engineering; thin-walled beam theory; finite element; total longitudinal strength
