浮船坞横向强度的有限元法评估基

Transverse Strength Evaluation Based on Finite Element Method of Floating Docks

针对浮船坞的横向强度评估问题,根据中国船级社《浮船坞入级规范》(2009)的要求,给出了外载荷计算方法和施加方式,采用大型通用有限元软件Patran建立有限元模型并进行结构计算,与强度衡准进行比较,结果表明本文方法方便可靠,可以为此类船型的横向强度计算提供参考。

This paper focuses on the transverse strength of floating docks and presents a whole evaluation procedure according to the requirement of the CCS’s Rules for Classification of Floating Docs （2009）. The calculation method of environmental loads and application method are proposed. The FEM model is built by the Patran software to get the stress response and rule criteria are adopted to evaluate the transverse strength, the results show that the transverse frame is safety. The procedure will provide reference for transverse strength calculation of similar type foating docks.
