摘要/Abstract

摘要： 电磁轨道炮在发射过程中,由于强变电流产生的冲击力的影响,轨道会发生一定程度的变形,导致轨道炮的口径产生扩张,影响轨道炮的重复稳定发射。针对电磁发射轨道的扩张问题,构建出一套高速线阵CCD 测量系统对扩张的轨道口径进行测量,采用软件处理方法对采集的图像信息进行分析处理。试验研究表明:轨道口径的变形量与发射电流之间存在一定线性比例关系。构建的高速线阵CCD 测量系统可以瞬间在亚像素级上对电磁发射轨道的扩张变形量进行精确表征。

Abstract: During the electromagnetic launching process, the caliber of electromagnetic railgun may be expanded due to the electromagnetic force generated by the acute current. The caliber expansion has an effect on the repeated launch stability of the electromagnetic railgun. A novel high-speed linear array CCD measurement system was developed to detect this caliber expansion. The images obtained by the measurement system are analyzed using software methods. The results show that there is a linear relationship between caliber expansion and launching current, and the higher the launching current is, the larger the caliber expansion value is. The high-speed linear array CCD measurement system can measure the deformation of expanded caliber precisely in the sub-pixel dimension in a very short time.

Key words: ordnance science and technology, electromagnetic launch, caliber expansion, high speed linear array CCD, image segmentation
