摘要
基于ABAQUS软件将各站所受外力转化成节点力施加到船体结构上,分析结果表明,在舰船剖面上,距离中和轴越远,应力就越大,因此就越危险,这也是被校核的位置,且与参考值比较可知有限元法在这些位置的计算结果的误差很小。只要施加合理的边界条件,所采用的计算方法可以满足工程要求。
On based the bending theory of beam, maximal stress of the ship＇s most dangerous section is obtained. In this article, all the applied forces are transformed into nodal forces on the hull structure using ABAQUS. The result indicates that the more the position for analysis is far from the neutral axis on the section of ship, the more stress can be generated, and in which is the most dangerous and also should be checked. The error of calculation result obtained by FEM is slight when compared with reference value. On all accounts, the calculation method in this article can meet the requirement of engineering if the boundary conditions are reasonable.
