| 摘 要： | 为了避免玻璃钢游艇在角隅区域产生疲劳裂缝,对船体结构造成危害,需要对该部位进行强度校核。在研究玻璃钢游艇的基础上,用ANSYS软件建立大开口舷侧板架有限元模型,采用层合壳单元处理复合材料和复合材料夹层结构并计算分析其结构强度,试航结果表明,计算结果可靠。 |

| Abstract: | Large openings may weaken the strength of the side plate and the sudden geometry mutation may course significant stress concentration in the corner to generate fatigue crack which is harmful to the hull structure.So the designers need to calculate the strength directly.In this paper,ANSYS software was used to model the FRP sandwich side plate with large opening to calculate the global deformation and stress distribution.The composite material and sandwich structure were simulated with layered shell elements... |
