【摘要】 讨论了船舶结构分析中的结构模型化问题，提出一种适用于船体舭部、肘板等特殊部位的有限元与边界元耦合模型，解决单纯用有限元法难于处理的问题。此方法已用于船舶结构直接设计分析系统（DDASSV1.0），在初步设计中可一次获得较满意的纵横强度，多数情况下不需要进行再分析。因此，本方法可大大减轻前后处理的工作量，并能保证良好的精度。更多还原

【Abstract】 The finite element modelling of ship structures is discussed and a coupling method of finte element is proposed.This method is suitable for analysis of particular parts of ship structures such as bilge and brackets and it is more efficent than that of the purefinite element analysis.This method has been shown that the preprocessing work is greatly reduced and the accuracy is improved.更多还原
