摘要：

针对传统荧光磁粉探伤方法中存在中波紫外辐射严重、工作环境恶劣、容易造成漏检等问题，优化设计了车轮表面荧光磁粉探伤系统的前端光源部分。采用LED紫外光源作为激发光源，实现了紫外光源的发射光谱与荧光磁粉的激发光谱的匹配。将108个LED紫外光源排列成面板阵列实现了高强度均匀光照，并将其辅以滤波片，过滤了光源中的有害紫外线和无用可见光。结果表明所设计的LED紫外光源满足了车轮表面荧光磁粉探伤系统的要求。

Abstract:

In view of severe radiation of UVB, bad on-site working conditions, easily leading to missed detection of traditional phosphor magnet powder flaw detection methods, the light source of phosphor magnet power flaw detection for tyre surface is optimally designed. A UV-LED light source is adopted as the excitation light source, it achieves matching between the UV-spectrum and the excited spectrum of the phosphor magnet powder. 108 UV-LED light source arranged in arrays to obtain the high intensity and uniform illumination.The LED light source with filter glass filter out harmful ultraviolet ray and useless visible light. The results show that the designed UV-LED light source meet the requirements of phosphor magnet power flaw detection for tyre surface.

Key words: linear CCD, magnet power detection, ultraviolet radiation B, LED light source
