摘　　要：船舶设计与结构分析是保证船舶安全的基本前提,而如何更有效对船体进行设计和结构强度分析对于船舶安全具有重要意义。通过充分利用DNV的Sesam软件和MSC.patran以及MSC.Nastran几个软件的优势,以对一艘3600DWT双底双壳超规范油船进行了屈服强度和屈曲分析,以及找出船舶在不同工况下所对应的承载规律,对于正确地进行非规范船结构强度直接计算具有指导作用和实用价值。Ship design and structural analysis is the prerequisite to ensure ship safety, moreover, how to undertake more effectively on the hull design and structural strength analysis is very important for the safety of the ship. By taking full advantage of both the DNV Sesam and MSC, Patran and MSC Nastran software, through the calculation and analysis of the yieM strength and the buckling for a 3600T double bottom double-hull supergauge tanker, it is found that the law of the bearing capacity of the ship in different loadcase .we can see that the method for unconventional ship design and strength analysis in accuracy and validity is of great significance.
