温压战斗部爆炸冲击波对地下目标毁伤建模

摘要

The thesis builds a three-dimensional model with ANSYS/LS-DYNA on the blast wave damage of Thermo-baric Warhead to Underground Objects, simulates the process of the explosion and the shock wave propagation in the underground hermetic roomage, acquires the overpressure curve corresponding to the blast wave characteristic of Thermo-baric Warhead and the curve of specific impulse by integral operation, and offers statistics elements to damage analysis.%针对温压战斗部对地下目标的冲击波毁伤问题,利用ANSYS/LS-DYNA有限元软件建立三维模型,模拟出炸药起爆以及冲击波在地下密闭空间中传播的全过程,得到了与实际密闭空间中温压炸药爆炸冲击波特性较为吻合的冲击波超压曲线,通过LS-DYNA自带的积分运算功能求得了相应的比冲量曲线,为下一步毁伤分析提供了数据基础.
