摘要
目前各大船级社普遍缺乏新颖玻璃钢艇体结构强度的计算规范,因此设计者需要直接计算艇体结构强度。在研究玻璃钢游艇的基础上,用ANSYS软件建立全船有限元模型,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整船结构强度。分析中所采用的方法对于正确地进行玻璃钢游艇整船直接计算具有指导作用和实用价值。同时所采用的冲击力和水动力加载方法可应用于其他类型的高速艇结构强度的有限元分析。
The codes and regulations provided by the major ship classification societies for computing strength of fashionable FRP yacht are very rare.Therefore,designers turn to the direct method to compute the structural strength.Based on the study of FRP yacht,a finite element model of full yacht was generated by software ANSYS with layered shell elements to treat composite materials and sandwich structures as well as to compute the structural strength of the full model.The methods used in the paper have provided some advices on how to perform direct computations of FRP yacht in a right way and therefore are of practical values.The two loading methods applied in this paper,impulsive forces and hydrodynamics,can also be used to perform finite element analysis for other similar boats of high speed.
