摘要: 玻璃钢复合材料作为一种新型的工业材料,被广泛应用于包括造船行业在内的诸多领域当中。在船体设计时,为了避免因碰撞等外力因素造成船体损伤,需要事先对其相关结构的力学性能进行数值分析。以带有大开口的玻璃钢游艇舷侧夹层板架结构作为研究对象,对该结构的相关力学性能进行了有限元分析,并对其位移变形量和应力分布情况进行了校核。按照此种方式,分别计算了不同大小的静压力载荷、不同大小的冲击载荷、不同的开口形状和尺寸以及不同的载荷作用位置等诸多工况下的仿真算例,分析、比较其计算结果,最终得出结论。

Abstract: FRP composite material is a new type of industrial materials, which is widely used in many fields, including the shipbuilding industry. In the design of FRP hull, we must make a simulation of related structure′s strength and stiffness in advance for avoiding ship hull damage caused by external forces such as collision. In this paper, the FRP Yachts sandwich plate frame structure with large openings were selected as the object of our research, and the finite element method was used to analyze the mechanical properties of the target structure. Based on the calculation results, the displacement and stress distribution of the target examples were checked. In this way, the effects of various operating conditions on mechanical properties of the target structure were obtained, and some meaningful conclusions were proposed at the end of this article.

Key words: FRP composite material, mechanical properties, finite element analysis, impact load
