摘要/Abstract

摘要： 采用基于脉冲反射模式的自动化相控阵超声检测技术,对复合材料帽形长桁加筋曲板结构进行自动化检测研究。分别针对曲面蒙皮和帽形长桁R角结构,选取不同探头、不同频率、不同聚焦方式,开展相控阵自动化检测仿形、C扫描成像及缺陷判定。结果表明,采用超声仿形测量的方法实现曲面蒙皮的自动化检测,能够检测出最小达Φ3 mm的缺陷;针对帽形长桁R角结构特点制定特殊的R角水靴,实现R角的自动化相控阵检测。

Abstract: Compared with other non-destructive testing technologies, ultrasonic testing is still the most widely used and mature technology for aeronautical composite component testing. In recent years, with the gradual development of domestic phased array ultrasonic testing technology, this technology has gradually moved from the laboratory research stage to the production inspection application stage. The Automatic phased array ultrasonic inspection technique based on the pulsed echo mode was utilized to study the automatic inspection of composite omiga stringer stiffened curved panel. For the curved panel and omiga stringer R structure respectively, different probes, frequencies and focus modes were used to carry out automatic inspection and profile, C scan imaging and defect evaluation. The results prove that the automatic inspection and profile of curved panel can be realized by utilizing ultrasonic profiling measurement method, and the minimum size to Φ3 mm defect can be detected. The omiga stringer R structure can be inspected automatically by customizing the special R structure water shoe.

Key words: composites, omiga stringer stiffened curved panel, curve profile, automatic phased array ultrasonicinspection
