汽车滚装船抵抗挠曲变形的构造分析
|
摘要
以某汽车滚装船为例,运用有限元计算软件FEMAP with Nastran分别建立初始状态、典型横舱壁方案以及其他构造考虑方案的整船体模型,探讨各方案的构造特点及在各层甲板处的相对挠曲变形量,以典型横舱壁方案在整船抵抗挠曲变形上的能力值为参考,对比各模型的计算,结果表明,双壳构造结合梯道围壁的方案与典型的横舱壁设计方案相比较,在整船抵抗挠曲变形能力上有一定的近似性。
Taking one PCC as an example,the finite element software FEMAP with Nastran was used to build the whole ship model of the primitive case,typical transverse bulkhead case and other cases. The different characteristics of the racking constraining structures were explored,and the racking deformation results were compared. Taking the racking constraining capacity of the typical transverse bulkhead as reference,it was concluded that the racking constraining capacity of the double hull structure combined with stair casing structure is similar to the typical transverse bulkhead case.
