杀爆战斗部破片对厚壁钢管的毁伤效应研究

采用静爆试验与数值仿真的方法，研究了杀爆战斗部破片对厚壁钢管的毁伤效应。根据Tresca准则和厚壁圆筒强度理论，给出了厚壁钢管的失效判据。研究了破片形状、着角、质量、速度等因素对毁伤效果的影响。研究结果表明，杀爆战斗部在厚壁钢管侧方或前方近处爆炸，形成的破片对厚壁钢管有较为明显的破坏效应。所给出的数据及对毁伤规律的分析，对厚壁钢管生存能力的分析和战斗部的设计与改进提供了参考依据。

Research on Thick Barrel's Damages Due to Impaction by Fragments of High Explosive Projectile

Explosive test and numerical simulation were carried out to examine the damage effects of high explosive projectile to thick tube. According to Tresca guide line and thick cylinder's strength theories, the criteria of tube's failure were deduced. The effects of fragment's figure, aviation direction mass, velocity on damage were explored. The research results indicate that if high explosive projectile explodes near or in front of the thick steel tube in some short distance, the generated fragments' impactions will cause clear damages to the steel tube. The given data and the analyses to damage law can be used as reference basis to analyses of thick tube's viability and to design and improvement of warhead.
