摘要
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,a calculation model for ship hulls is established by Vlasov's semi-moment theory of shells and the relations between this theory and thin-walled beam theory, frame method are discussed. The methods of treating distorsional angles uncompatibility between different sections, members of ship's hull and distributed loads on ship's surface have been provided for the purpose of application.The proposed method is able to comprehensively take into account the coupled responses of tension/compression,bending, torsion as well as transverse deformation to ship's hull, and it has an obvious advantage over FEM in data quantity and calculating time.
