摘要
针对中大口径弹药装药密度无损检测中壳体边缘效应的影响,提出采用建模修正和去壳修正两种方法,优化现有的密度对比法模型。对比两种修正方法的测量结果表明,对于钢制壳体弹药装药密度检测,去壳修正法的测量精度要优于建模修正法。研究内容对弹药装药局部密度的工业计算机断层成像检测具有一定指导意义。
Modeling and decladding corrections are adopted to research the edge effect of shell inthe quantitative inspection of charge density of medium and large caliber ammunition by industrial CT imaging.The accuracy of density comparison model can be improved.The test results show that the accuracy of decladding correction methodis better than that of modeling correction method for charge density inspection of ammunition.The proposed methods can be used for the inspection of local charge density by industrial CT imaging.
