摘要/Abstract

摘要： 在船用可回转推进器结构设计方案的基础上,完成了碳纤维复合材料叶片的设计制造。结合计算流体动力学(Computational Fluid Dynamics,简称“CFD”)方法获得了复合材料螺旋桨叶片的等效最大设计载荷,最后通过设计相应的试验装置对复合材料叶片进行了疲劳寿命与剩余强度的试验。研究结果表明,在经过百万次疲劳载荷作用后,叶片无肉眼可见损伤,叶片的剩余强度远大于极限载荷,该复合材料螺旋桨叶片的材料结构设计与制造工艺满足工程使用要求。

关键词: 碳纤维复合材料, 螺旋桨叶片, 疲劳试验, 剩余强度

Abstract: The blade of marine all-direction propeller was prepared from CFRP, which was designed and manufactured based on structure design of whole machine. The maximum design load is equivalent from pressure on blade surface under limited conditions by CFD method. Finally, fatigue test and residual strength test are completed on the specially designed device. The results show that the propeller blades don′t have any visible damage after fatigue test and the residual strength is far above limited strength. The structure design and manufacturing process of composite blade meet marine propeller′s requirements.

Key words: CFRP, propeller blade, fatigue test, residual strength
