Design and Simulation of Shock-Release-Reshock Experimental Device for TATB-Based Insensitive Explosives under Detonation Loading
在一些特殊的工程应用和意外事故中,炸药内部可能会受到多次冲击压缩和卸载作用从而使其起爆性能发生变化,因此,需要一种可以模拟多次冲击和卸载的实验加载装置,用以研究炸药在复杂载荷下的起爆响应.基于爆轰加载原理,提出并设计了一种可以实现完全卸载的冲击-卸载-再冲击的爆轰加载实验装置,利用数值模拟对该装置进行了仿真设计和参数优化,并通过实验验证了数值模拟的准确性和装置设计的可行性.结果表明:利用所设计的爆轰加载装置驱动钨镁双层飞片撞击TATB基钝感炸药,通过调整装置中的间隙宽度,可以对炸药实现完全卸载的冲击-卸载-再冲击加载,为后续研究炸药在复杂载荷多次冲击下的起爆响应提供了一种新的实验技术.
In some engineering applications and accidents,the detonation performance of explosives may change if subjected to multiple shocks and releases.Therefore,an experimental loading device with multiple shocks and releases is needed in order to study the detonation response of explosives under complex loads.In this paper,an experimental detonation loading device that can achieve complete release of shock-release-reshock is proposed and designed.The device is optimized through numerical simulations,and the accuracy of the numerical simulation is validated by the corresponding experiments.The results indicate that the designed detonation loading device can achieve complete release of shock-release-reshock loading procesure of TATB-based insensitive explosives,where the detonation loading device drives tungsten magnesium double-layer flyers.The design provides a new experimental technique for further study on the detonation response of explosives under complex loads and multiple shocks.
