摘要

激光切割在制造业中的应用越来越广泛,而铝合金飞机蒙皮材料对激光的吸收率低,激光切割质量较差,所以在激光切割在蒙皮的加工制造过程中一直没有得到应用。为了探索飞机蒙皮材料的激光切割性能以及切割后其力学性能的变化,对激光切割试件进行了表面形貌分析、显微硬度测试以及拉伸、压缩、剪切测试。试验结果显示,试件激光切割后出现了明显的挂渣,拉伸强度略有下降,压缩和剪切强度没有变化。因此只要优化激光切割工艺,提高切割质量,激光切割技术就可以推广应用到飞机蒙皮材料的边缘切割。

Abstract

Laser cutting technology is widely used in manufacturing industry. But the laser absorptivity of the aircraft skin material is low,and the laser cutting quality is poor,so laser cutting is not applied in manufacturing of the aircraft skin. In order to searching laser cutting performance of the aircraft skin and the change of its mechanical properties by laser cutting,the surface topography analying,micro-hardness testing and tension,compression and shear test were carried used laser cutting test sample.The test result show that the test sample emerged freeze slag after laser cuting,and its tensile strength decreased slightly,but compression strength shear strength retained original level. So laser cutting technology can be used in edge manufacturing of the aircraft skin by improving the laser cutting process and rising the laser cutting quality.
