摘要
SiC/Al复合材料具有较高的强度、较低的热膨胀系数和较好的耐腐蚀性,使其在多个高技术领域中具有很大的应用潜力和价值。然而,由于SiC/Al复合材料的高硬度特性,使用传统切削技术对其进行加工时,刀具磨损严重,影响加工效率。而激光切割技术在SiC/Al复合材料加工方面具有显著优势。文章利用有限元分析软件对SiC/Al复合材料进行仿真分析,了解材料特性和激光切割去除机理,探究加热时间、光斑尺寸等对材料表面温度场的影响。
SiC/Al composites have high strength,low thermal expansion coefficient and good corrosion resistance,which makes them have great application potential and value in many high-tech fields.However,due to the high hardness characteristics of SiC/Al composite materials,the tool wear is serious when it is processed with traditional cutting technology,which affects the processing efficiency.Laser cutting technology has significant advantages in the processing of SiC/Al composite materials.In this paper,finite element analysis software is used to simulate SiC/Al composites,understand the material characteristics and laser cutting removal mechanism,and explore the effects of heating time and spot size on the material surface temperature field.
