聚能射流作用于带壳B炸药非爆轰解体的研究
Study on Disintegration without Detonation of Shelled Composition B Penetrated by Shaped Charge Jet
摘要
Abstract
In order to optimize the structural parameters of conical shaped charge and explore the conditions for achieving disintegration without detonation of shelled Composition B,the jet formation process was simulated using AUTODYN software based on orthogonal experimental method.The influences of different charge structural parameters such as cone angle,material,wall thickness,and charge diameter on the jet detonation capability v2d were studied.And the structural parameters for penetrating shelled Composition B were optimized.Simulation of penetration of steel shelled Com-position B with projectiles was conducted using the selected charge structure.The effects of explosion height and shell thickness on the response state of explosives were investigated.The mechanism of jet penetration and detonation of shell charges at different explosion heights was also analyzed.Finally,experimental research was conducted to verify the simula-tion results of the response state of explosives.It was found that,for the selected shell steel shell and 20 mm caliber energy gathering charge,when the explosion height is less than 3.50d(shell thickness of 0.2d)or d(shell thickness of 0.3d),Compositon B detonates under the action of the shock waves directly generated by jet penetration or the reflected waves obtained from shock wave contact with the back plate.When the explosion height is greater than 5.00d(shell thickness of 0.2d)or 2.05d(shell thickness of 0.3d),the shock wave and reflected wave generated by the residual energy of the jet could not cause the detonation of Compositon B,and disintegration without detonation of the ammunition could be achieved.关键词
