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。
When the warship has a superstructure with longer length and more openings, the complexity of the hull structure makes it difficult to determine the total hull strength by the conventional beam theory. In this paper, the whole ship three-dimensional finite element method is used to calculate the total longitudinal bending deformation and stress distribution of the designed ship through the whole ship loading and inertia balance treatment, and the validity of the superstructure participation in the hull longitudinal strength, Nuclear provide the basis.
