摘要

爆炸冲击波压力是弹药爆炸过程中产生的主要毁伤参数之一,也是评价弹药毁伤威力的重要技术指标。但在实际测试过程中,只能获得有限数量的特定测点的冲击波压力数据,无法准确反映弹药爆炸后冲击波压力传播的分布规律。因此,基于有限的测点数据重建冲击波压力场分布规律就显得尤为重要。本文综述了国内外研究人员在爆炸场冲击波压力分布规律重建方面的研究工作和取得的相关成果。本文还阐述了计算机断层成像技术、冲击波传播衰减模型重建以及各种插值算法在冲击波压力场重建过程中的相关应用。结合国内外研究现状,我们明确了现阶段研究中仍存在的主要问题,并提出了今后研究中需要关注的重点领域。

Review of shock wave pressure reconstruction methods in explosion field
Explosion shock wave pressure is one of the main damage parameters produced in the process of ammunition explosion, and it is also an important technical index to evaluate the damage power of ammunition. However, in the actual testing process, only a limited amount of shockwave pressure data at specific measuring points can be obtained, which cannot accurately reflect the distribution laws of the shockwave pressure propagation after the ammunition explosion. Therefore, it is particularly important to conduct reconstruction of the shockwave pressure field distribution laws based on limited measuring point data. This paper reviews the research work and related achievements obtained by researchers at home and abroad on the reconstruction of shockwave pressure distribution laws in explosion fields. The paper also elucidates the relevant application of computer tomography imaging techniques, shockwave propagation attenuation model reconstruction, and various interpolation algorithms in the reconstruction process of the shockwave pressure field. Given the current research situation both domestically and internationally, we have pinpointed the major issues that still exist in the current stage of research and proposed the key areas of focus that need attention in future research.
