摘要
为比对分段建模与整体建模工作量及稳性计算结果,选取某浮船坞,采用命令流方法,对坞墙无开口,做5 分段建模和整体建模稳性计算,对坞墙有开口,做7 分段建模和借助体过渡整体建模稳性计算,结果表明,无论坞墙有无开口,整体建模比分段建模节省约一半工作量,两种建模方式稳性计算精度相同,建模过程表明,命令流方法整体建模计算稳性,高效快捷.
Abstract
In order to compare workload and accuracy between subsection modeling and holistic modeling of stability analy-sis,3D modeling and stability analysis were carried out for a real floating dock.For dock wall with no opening,5 subsections modeling and holistic modeling were built by using the command method;and for dock wall with 4 openings,7 subsections mod-eling and holistic modeling were built by body transition.It was shown that compared with subsection modeling,the holistic mod-eling saves about half of the workload,no matter what dock wall with or without openings;both modeling methods have the same stability analysis accuracy.The holistic modeling by command flow method is quick and efficient for stability analysis.
