【摘要】 当舰船设有长度较长但开口较多的上层建筑时,其船体结构的复杂性使船体总强度很难用常规的梁理论方法确定。本文采用整船三维有限元分析方法,通过整船加载和惯性平衡处理,计算出设计目标船的总纵弯曲变形和应力分布,以及上层建筑参与船体总纵强度的有效度,为船体总强度校核提供依据。更多还原

【Abstract】 For a naval ship with a long strength superstructure and a lot of hatch, it is difficult to evaluate the hull girder’s strength by general beam theory because of the complexity of the hull structure. In this paper,3-D FEM for the global ship,by adding loads and inertia adjustment, is used to calculate its longitudinal strengh,longitudinal bending distortion and stress distribution, and the efficiency of the superstructure to stand against longitudinal strength,which present a foundation for the check of ship’s longitudinal strength.更多还原
