针对复合材料各向异性严重导致设计困难的问题,采用复合材料结构分析与设计软件Hypersizer建立模型,进行铺层设计和铺层过渡设计。首先,将模型划分成不同的设计区域,根据不同设计区域的受载情况进行分析计算,设计铺层厚度、铺层比例和铺层顺序。然后,在铺层过渡区设计铺层递减方式,并按照铺层设计原则重新调整原先的铺层。最终得出满足符合工程实际要求的最佳铺层和铺层过渡。 Aiming at the problem that the anisotropy of composite materials seriously lead to the design difficulties, a model was established by Hypersizer, a composite structural analysis and design software, to design the ply and the ply transition. First, the model is divided into different design areas. According to the loading conditions of different design areas, the model is calculated and the ply thickness, ply ratio and ply order are designed. Then, in the transition zone design ply descending way, and in accordance with the principle of ply design to re-adjust the original ply. Finally, it is concluded that the best ply and ply transition to meet the actual engineering requirements.
