Northwest Institute of Nuclear Technology, Xi'an 710024, Shaanxi, China

摘要

摘要: 对内聚滑移爆轰加载下圆管压缩运动过程进行工程分析，分析解与数值模拟结果吻合。利用工程模型得到了不同管道参数（包括内径、厚度）下管道封闭所需要的炸药量和封闭时间表达式，可为相关研究工作提供参考。

Abstract: By making some assumptions, an analytical model was presented to analyze the compression process of the cylindrical metal tube subjected to an inward sliding detonation.And the corresponding numerical simulations were carried out to verify the analytical results.The analytical results agreed well with the numerical ones.So by fitting the analytical data, two expressions were obtained for the explosive thickness needed to close the tube and the tube closing time, respectively, in which involving different tube parameters such as tube inner diameter and wall thickness.
