摘要：

为得到碳纤维在无人机叶片中最优的铺层方式,通过Workbench中的ACP(ANSYS Composite PrepPost)模块,对碳纤维复合材料无人机叶片的铺层进行设计。利用SolidWorks三维建模软件建立无人机叶片的三维模型,并采用HyperMesh对叶片进行几何清理、划分网格等,利用Ansys Workbench Fluent对无人机叶片的不同转速进行流体仿真,提取叶片表面压力载荷,对不同铺层的碳纤维复合材料无人机叶片进行仿真与分析,得到碳纤维复合材料无人机叶片的力学仿真结果,并基于Tsai–Wu失效准则,计算每层铺层的失效系数,进而对比得出最优的碳纤维铺层方式为[0°,90°,90°,90°,0°]。

关键词: 碳纤维复合材料, 无人机叶片, 流体仿真, 铺层设计

Abstract:

In order to obtain the optimal layering mode of carbon fiber in unmanned aerial vehicle(UAV) blade, the layering mode of carbon fiber composite UAV blade is designed through ACP (ANSYS Composite PrepPost) module in Workbench. The three-dimensional model of UAV blade is established by using SolidWorks three-dimensional modeling software, and HyperMesh is used to clean and mesh the blade. Ansys Workbench Fluent is used to simulate the different speeds of UAV blade, extract the pressure load on the blade surface, and simulate and analyze the carbon fiber composite UAV blades with different layers. The mechanical simulation results of carbon fiber composite UAV blades are obtained. Based on Tsai–Wu failure criterion, the failure coefficient of each layer is calculated, and the optimal carbon fiber layering mode is [0°,90°,90°,90°,0°].

Key words: carbon fiber composite, unmanned aerial vehicle blade, fluid simulation, layer design
