摘要根据转子叶片的曲面特性和服役环境,开展了复合材料叶片曲面可铺性分析研究,提出了一种基于预浸料纤维变形及纤维铺放方向双约束的复杂曲面复合材料构件可铺性分析方法,该方法既满足了复合材料构件曲面铺放工艺性要求,同时又满足构件结构承载要求。基于CATIA Automation技术在Visual Basic 6.0平台上开发了相应软件模块,利用叶片模型仿真验证了该算法。
关键词:复[ABSTRACT] According to the provided geometric model and service environment of the blade, the paper promotes the study about placeability technology on complex surface of the composite blade model and raises an analytical method about complex surface of composite component based on fiber deformation constraints and ply-orientation constraints. The method can not only satisfy the placeability character but also guarantee the mechanical properties. The algorithm is programmed through Visual Basic 6.0 compile software module by using automation technology based on CATIA and simulation verification is done by using the blade model.
Keywords: Composite material Rotor blade Placeability analysis Fiber deflection Ply-orientation
