摘要
水中爆炸冲击波对鱼雷进行爆炸冲击毁伤,是拦截鱼雷的主要手段。从炸药包起爆开始,用有限差分方法对无限均质水介质中球形药包起爆后激发的冲击波载荷进行了数值仿真,并用实验数据对计算结果进行了对比验证,结果表明方法合理可行。该技术能为今后开展水下爆炸对鱼雷杀伤能力的仿真与评估研究提供技术支撑。
Underwater explosion shock wave is the primary measure to hold up torpedo. The numerical simulation of shock wave loads for underwater spherical explosion in infinity uniformity water medium by using the finite difference calculation method and the calculation data is validated by experiment data. The result is show that the numerical simulation investigation technology is feasible and can support the simulation and evaluation technology of underwater explosion damage to torpedo.
