本文应用半无矩壳理论建立了船体结构计算模型并综合讨论了该理论与薄壁梁理论和刚架位移法的关系。在船体实用计算中,提出了不同剖面间畸变角协调、船体纵横骨架和面外分布载荷等的处理方法。本文方法能综合考虑船体拉(压)、弯、扭及横向变形的耦合响应并且比常规有限元法大大节省机时和人力。
In this paper, the hull structure calculation model is established by using semi-no-crust case theory and the relationship between the theory, thin-wall beam theory and rigid frame displacement method is discussed. In the practical calculation of the hull, a method of dealing with distortion angle coordination between different sections, hull longitudinal and transverse skeletons, and out-of-plane distribution loads was proposed. This method can comprehensively consider the coupled response of hull pulling (pressure), bending, twisting and lateral deformation, and saves machine time and labor compared with conventional finite element method.
