摘要
为推动复合材料螺旋桨构件设计与成型工艺的一体化研究,发挥纤维混杂在高阻尼、高性能桨叶开发环节的助力作用,以小尺寸复合材料螺旋桨为对象,基于其叶片型面特点与几何特征,开展混杂纤维复合材料桨叶的选材与铺层设计等工作,确定了螺旋桨在碳纤维(CF)/芳纶纤维(KF)混杂方式下的两种铺层方案。借助ANSYS Workbench平台中的ACP模块,建立了与桨叶实际结构特征较为一致的复合材料各向异性有限元模型,并在仿真分析的指导下,使用预浸料的模压成型工艺制作了混杂纤维复合材料螺旋桨样件模型。通过静态加载试验和模态测试试验,对比了桨叶模型的静刚度和前三阶模态频率的测试结果与计算结果,这既验证了基于ANSYS ACP的复合材料螺旋桨建模方法的有效性,也验证了模压法制作混杂纤维复合材料桨叶样件的可行性。
In order to promote the integrated research on the design and molding process of.composite propeller products and emphasize the role of fiber hybrid in the development of high damping and high performance blades,the small-size.composite propeller was taken as an investigation object.Based on its surface and geometric characteristics,the material and ply design of the hybrid fiber.composite blade were carried out,which results in two propeller ply schemes under the hybrid modes of carbon fiber(CF) and kevlar fiber(KF) respectively.By employing the ACP module in ANSYS Workbench platform,the finite element modelling of anisotropic.composite material was conducted,which can be consistent with the actual structural characteristics of the blade.According to the guidance of simulation analysis,the hybrid fiber.composite propeller sample model was fabricated by using the molding process of prepreg.Through the static loading test and modal measurement test upon the manufactured propeller blade,the.comparisons between experimental and calculation data of its static stiffness and modal frequencies from the 1st to 3rd stage are obtained.The good agreement not only verifies the reliability of the modeling method of.composite propeller based on ANSYS ACP,but also verifies the feasibility of manufacturing hybrid fiber.composite blade samples by molding process.
