摘要
按照承受载荷的不同将船体中的板分为两种,即承受板中面内载荷的平面应力板和承受垂直于板中面载荷的弯曲板元。根据这两种分类将加筋板按不同的方法实现了结构正交异性向材料正交异性的转化,即将板上的加强筋按照一定的方法折合到所附连的板上,进而实现材料上正交异性板的有限元软件模拟。但这种转化并非是完全等效。文章提出了某些参数的修正方法,对实际工程中所关心的几个参数实现了统一。通过比较有限元的计算结果,表明正交异性板在特定工程领域中是可用的,对相关研究和工程计算具有一定参考价值。
The plates of ships are divided into two types according to the different load that the plate endured, that is the plate of plane stress which enduring the load of middle plane, and the bending plate which endures the load of that perpendicular to middle plane. Based on this classification, the orthotropic plate in structure can be transformed into that in material with different methods, which means the stiffeners are to be converted into the plates added on by a certain method,and in further, it simulates the orthotropic plate in material with finite element software. However,this transformation is not completely equivalent, therefore some correction methods paesented for some parameters to make the parameters concerned in the engineering field equal. By comparing the results obtained from the finite element software, it shows that the perpendicular orthotropic plate is practicable in some engineering field, and the results of the work has some referential values to the related research and engineering calculation.
