摘　　要：主船体建筑受到力的作用时,部分位置的结构容易出现应力集中情况,影响主船体的结构安全,针对该问题构建分析主船体建筑结构强度的钢质模型。建立包含平衡微分方程、物理方程、边界条件的弹性力学方程,分析主船体建筑结构受到载荷作用时的应力变化。分析主船体建筑结构强度钢质模型的几何相似关系,采用不同缩尺比缩放处理钢质模型与主船体建筑结构。选取大尺度钢质模型,利用Ansys有限元分析软件,构建主船体建筑结构强度钢模的有限元模型,明确主船体建筑结构强度变化。实验结果表明,所构建的主船体建筑结构强度钢模,可有效分析不同大小载荷作用时的结构强度变化,结构强度分析结果与实际强度相差较小。When the main hull building is affected by the force,the stress concentration of some parts of the structure is easy to affect the structural safety of the main hull.The elastic mechanics equation including equilibrium differential equa-tion,physical equation and boundary condition is constructed to analyze the stress change of the main hull building structure under load.The geometric similarity relationship between the steel model and the main hull building structure is analyzed,and the steel model and the main hull building structure are scaled by different scale ratios.The large-scale steel model is se-lected as the steel mold of the main hull building structure.Using Ansys finite element analysis software,the finite element model of the structural strength steel die of the main hull building is constructed to determine the change of the structural strength of the main hull building.The experimental results show that the structural strength steel mold of the main hull building can effectively analyze the change of structural strength under different loads,and the difference between the ana-lysis results and the actual strength is small.
