| dc.description.abstract | 本文之主要目的在透過有限元素分析，探討貨櫃船船艏bow flare在波擊及plunge時之結構強度；在數值解析方面，利用有限元素分析軟體MSC/Patran和Nastran作為分析工具。
在波擊情況中，以一實際受損貨櫃船做為樣本船，建立船艏結構有限元素分析模型，波擊負荷利用船籍協會法規計算，對其進行應力與挫曲分析，並根據分析結果，對結構發生損傷部位加以補強；在plunge情況中，以相同貨櫃船做為樣本船，建立結構分析模型至第三貨艙區，plunge負荷則依據不同吃水深度而定，以應力分析結果，探討第一貨艙區之結構強度；藉由本研究方法之分析結果，作為日後船體結構設計時之考量依據。 | zh_TW |
| dc.description.abstract | The purpose of this article is to study the strength of containership due to bow flare slamming and plunge by using FEA (finite element analysis). In the numerical analysis, finite element software, MSC/Patran and Nastran, is the analytic tool.
In slamming case, an actual containership with damage in bow structures is used as the sample ship to establish FE (finite element) model including bow structures. The slamming impact loads used in the calculation are obtained from rules of classification society and then applied to the analysis of the static and buckling. According to the results of the analysis, we stiffen the structures with damage. In plunge case, the sample ship is same as slamming case, and the established FE model is extend to NO.3 cargo hold. The loads due to plunge are according to different draft, then, confer the strength of structures connected NO.1 cargo hold by the results of static analysis. According to the results obtained from this research approach, use it for the basis about the design of ship structures in the future. | en |
