BV公開程應用於FRP上層結構設計

APPLICATION OF BV PACKAGE TO FRP SUPERSTRUCTURE DESIGN

世界各國海軍在新一代軍艦的設計上，均大量使用FRP做為船身與上層結構的建造材料，本研究參考一般FRP軍艦的上層結構外型，使用BV公開程式Compose-IT進行FRP軍艦上層結構的規範設計，並假設設計之上層結構除了基本的裝備壓載外，需額外再承受最大100節的風壓負荷。本研究將規範設計而得之上層結構，進一步使用有限元素分析軟體ABAQUS進行結構強度分析，確認在風壓與樓板負荷共同作用下，所設計之結構能具有足夠的強度。接著在維持足夠結構剛性的考量下，進行樓板開孔與結構補強，並根據數值模擬結果確認結構佈置，最終完成FRP上層結構之規範設計。 FRP had been widely utilized in new war ships’ construction, included hulls and superstructures. In this study, we referred to the general appearance of war ship’s superstructure and used BV open package Compose-IT to de-sign the stacking arrangements. The loadings considered in this study were general weights of equipment and extra maximum wind pressure reached to 100 knots. Furthermore, ABAQUS was used to simulate and verify the strength of designed superstructure when it subjected to specific loadings. In order to maintain enough structure rigidity, we used top-hat stiffeners to reinforce the rigidity of opening and FRP plate, and confirmed the structural response by numerical simulation results. Finally, we have successfully used the specification to design FRP superstructure.
