摘要/Abstract

摘要： 在弹药装药底隙检测中，运用密度对比法结合体积效应，将底隙测量转化为弹底密度变化的测量，建立弹底扫描断层中心部位计算机断层成像（CT）值变化与底隙值之间的数学模型，解决底隙测量理论与实际操作中的难题。预置底隙测量实验结果表明：该模型可完成对0.20~0.50 mm底隙的测量，最大相对误差小于3.5%，可实现对装药底隙的定性判断与定量检测。

Abstract: A volume effect of industrial computed tomography(CT) imaging and a contrast method for density inspection are used to build an algebraic model for base separation inspection, which improves the base separation inspection method in theoretical and practical ways. The size information is qualitatively and quantitatively analyzed with high precision by the fluctuation of inspected CT values. The experimental results of base separation inspection show that the density contrast model is suitable for the inspection of 0.20~0.50 mm base separation, and the relative error is less than 3.5%.

Key words: ordnance science and technology, industrial computed tomography, density contrast, base separation, quantitative inspection
