某海洋试验船横向强度评估

Total Transverse Strength Evaluation of Ocean Research Ship

对于扁平状船舶来说,横向强度是一个非常重要的强度问题。本文参考中国船级社《国内航行海船建造规范》(2012)关于驳船横向强度的计算方法,利用大型商用有限元分析软件MSC.PATRAN/NASTRAN对船体结构进行应力分析计算,校核某海洋试验船的横向强度,验证了该船采用的横向框架结构的安全性。

This paper focuses on the total transverse strength of a ocean research ship. With the evaluationmethod reference to the CCS rule： Rules for classification of surface naval ship （2012）, the FEM model is builtby the Patran software to get the stress response and rule criteria adopted to evaluate the transverse strength. Theresults prove that the transverse frame are safety.
