激光切割对飞机蒙皮疲劳性能的影响分析
Effect of laser cutting on fatigue performance of aircraft skin
摘要
Abstract
In order to explore effect of laser cutting on fatigue performance of aircraft fuselage skin , by using the method of simulation and contrast test method respectively , fatigue performance of aircraft skin material was studied by theoretical analysis and experimental verification .Analysis data of finite element fatigue of aircraft skin material , and comparison data of fatigue performance test of laser cutting specimen and mechanical milling specimen were obtained .At the same time , fatigue fracture of aircraft skin plate was scanned and analyzed by scanning electron microscope .The analysis results show that after laser cutting , fatigue life of aircraft skin material is about 5.4 ×104.After mechanical milling, fatigue life is 2.34 ×105.Laser cutting has a certain impact on fatigue performance of aircraft fuselage skin materials , but its fatigue life can increase through grinding and processing of cutting seams .关键词
