Application of the Industrial CT Technology in the Ammunition Charge Density Difference Measurement
-
摘要: 采用两种方法对现有BT-400型工业CT无损检测系统进行了密度分辨率指标测定，得出该系统的密度分辨率为1.0%左右，并使用BT-400型CT设备对某战斗部装药完成了密度差测量，测量结果与这批样品开壳弹排水法结果进行了比较，装药密度测量误差小于1%，密度差测量结果在量值上一致。说明工业CT技术密度差测量方法可行、测量结果可信，具有一定参考意义。Abstract: This paper introduces two kinds of methods for the testing of the density resolution of the BT-400 type industrial CT nondestructive testing system. The density resolution of the system is about 1.0%, and the measurement of one warhead charging density difference is completed by the industrial Ct equipment. The results and the sample open shell drainage method results are compared. The charge density error is less than 1%, the density difference is consistent in magnitude. It shows that the density difference measurement method is feasible by industrial CT technology, the measurement results are reliable. It has some reference significance to the reader.
