SNAME关于求船体梁的刚度和质量的时候只是说:

Alternatively, the hull can be modeled by using a grillage of beams.  Deck, bottom, side shell and bulkheads can be used to construct the grillage.  The properties of the beam can be calculated based on the depth of the bulkheads, side-shell and the 'effective width' of the deck and bottom plating.  Attention should be paid to the in-plane and torsional properties due to the continuity of the deck and bottom structures.

各位在实际操作中是如何实现的呢?比如SNAME说可以简化模拟成一个梁栅格,Side shell ,transverse BHD, Long. BHD, Legwell,如果等效模拟?

根据SNAME,The properties of the beam can be calculated based on the depth of the bulkheads, side-shell and the 'effective width' of the deck and bottom plating.  这个过程如何实现?而且 effective width怎么取?是不是好像在rule里那样,half-span or  33% of the unsupported span?

如何等效质量??

欢迎大家指教..

没有做自升式平台的计算，啊

s是如sacs那样的简化成梁架么？
