초록
通过SPH方法,利用Fortran编程,首先对自由场中装药爆炸进行模拟,将结果与经验公式对比,验证Fortran程序的有效性和正确性.然后对浅水爆炸问题进行数值模拟,再现浅水爆炸的基本物理现象,研究浅水爆炸相对于无限水域爆炸所独有的压力和冲量特性;通过对浅水爆炸不同参数的研究,给出了不同爆深对压力和冲量的影响,分析水底泥沙密度对冲击波压力的影响,给出不同泥沙密度下浅水中压力的变化规律.研究表明,浅水爆炸同时受到水面和水底的作用,水面效应使压力曲线产生截断效应,底部效应会增加压力脉宽.随着爆深的增大,压力曲线逐渐由削弱峰值、削弱脉宽过渡为增大峰值、增大脉宽,冲量逐渐增大,水冢逐渐减小;随着泥沙密度的增加,浅水中压力峰值增大,作用脉宽也增大,直达波、水面反射波以及水底反射波的相互作用更加明显.本文研究旨在揭示上述问题的作用机理,总结规律性结论,为舰船水下爆炸结构响应预报和舰船结构的防护设计提供参考.
