|
Abstract:
以钢质壳体内部装填低X射线衰减特性含能粉体材料的点火器类火工品及类似结构火工装置为研究对象，设计加工模拟试件，利用数字射线成像检测系统与工业CT检测系统，通过实验摸索最优检测参数对研究对象进行有效检测成像；同时通过数字检测图像分析，确定封闭钢质壳体结构火工品内部低X射线衰减特性含能粉体是否装填。结果表明：能够通过数字射线成像检测系统与工业CT检测系统互补，对点火器类火工品及类似结构火工装置内部含能粉体是否装填有效判断。
This study took in-built energetic powdery material with low dose X-ray attenuation character in igniter within steel housing and its analogues as the major objects. Simulated specimens were designed and detected by digital radiographic detection system and industrial computed tomography (CT) detection system. The optimal parameters were explored by effectively imaging detection. In the meantime, image analyses through digital detection were used to make sure that in- built energetic powdery materials with low dose X-ray attenuation character were accurately loaded in sealed steel housing. The results revealed that digital radiographic detection system collaborated with industrial CT detection system might estimate the in-built energetic powdery material in ig-niter within steel housing and its analogues more effectively.
