摘要: 玻璃纤维增强复合材料有着质量轻、强度高的优良品质,特别适用于建造高速游艇等快速性高的小型船舶。然而关于玻璃纤维增强复合材料的船舶强度分析的研究相对较少,相关规范也不够完整。本文首先给出了采用夹层结构方法模拟玻璃纤维增强复合材料的建模方法;然后以某玻璃钢双体船为例,基于有限元的船舶强度直接计算理论,参照CCS的相关规范要求,给出了玻璃纤维增强复合材料双体船结构强度直接计算方法。计算结果表明,文中给出的玻璃纤维增强复合材料模拟方法能有效模拟该玻璃钢双体船的结构形式,且结构强度满足规范的要求,横弯工况为最易发生结构失效工况。文中所得结论对夹层结构玻璃钢船的研发设计具有参考意义。

Abstract: Glass-fiber Reinforced Composite(GRC) has the excellent quality of light weight and high strength, which is especially suitable for the construction of small ships with high speed such as high-speed yachts. However, the research on the ship strength analysis of GRC is relatively less, and the relevant specifications are not enough. Firstly, the modeling method of GRC with sandwich structure is presented. Then, taking a GRP catamaran as an example, based on the direct strength calculation theory of finite element method and referring to the relevant requirements of CCS, the direct strength calculation method of GRP catamaran is given. The results show that the GRC simulation method can effectively simulate the structural form of the catamaran, and the structural strength meets the requirements of the code, and the transverse bending condition is prone to structural failure. The conclusions drawn in this paper have reference significance for the development and design of GRP ship with sandwich structure.
