Underwater explosive load calculation and numerical simulation are the key issues of the design of underwater conventional weapons and protection of ships and submarine. Numerical simulation of underwater explosions involves large deformation, the moving material interface and multi-media coupling. It has brought a lot of difficulties and challenges to the grid-based numerical algorithm. The material point method (MPM) is a meshfree method and takes the advantages of the both Euler and Lagrangian methods. Extension of the material point method to the numerical simulation of underwater explosion and the multi-medium coupling process was introduced. At last, spherical TNT underwater explosion in one-dimensional and TNT underwater explosion in two-dimensional were simulated. Blast wave produced by TNT exploding was computed. The spatial distribution and variation of the explosion flow field parameters were analysed. The calculated results are in good agreement with the results of AUTODYN, empirical formula of Cole and SPH, and provide a important reference to engineering applications.

水下爆炸载荷计算与数值模拟是水下常规武器设计和舰船、潜艇防护设计中的关键问题。水下爆炸数值模拟中大变形、运动物质交界面和多介质耦合等问题,给基于网格的数值算法带来了很大的困难和挑战。物质点法是一种无网格粒子法,该方法继承了拉格朗日方法和欧拉方法二者的优点。将物质点法扩展到水下爆炸数值模拟中,介绍了水下爆炸数值计算中物质点法的多介质耦合计算过程。分别对TNT球形炸药一维水下爆炸和TNT炸药二维水下爆炸过程进行了数值模拟,计算了冲击波强度,分析了水下爆炸流场参量的空间分布和变化规律,并分别与AUTODYN、COLE经验公式和SPH方法计算结果进行了比较,结果吻合较好,为工程应用提供重要参考。

水下爆炸载荷计算与数值模拟是水下常规武器设计和舰船、潜艇防护设计中的关键问题。水下爆炸数值模拟中大变形、运动物质交界面和多介质耦合等问题,给基于网格的数值算法带来了很大的困难和挑战。物质点法是一种无网格粒子法,该方法继承了拉格朗日方法和欧拉方法二者的优点。将物质点法扩展到水下爆炸数值模拟中,介绍了水下爆炸数值计算中物质点法的多介质耦合计算过程。分别对TNT球形炸药一维水下爆炸和TNT炸药二维水下爆炸过程进行了数值模拟,计算了冲击波强度,分析了水下爆炸流场参量的空间分布和变化规律,并分别与AUTODYN、COLE经验公式和SPH方法计算结果进行了比较,结果吻合较好,为工程应用提供重要参考。

水下爆炸  /  物质点法  /  多介质耦合  /  数值模拟

Underwater explosive load calculation and numerical simulation are the key issues of the design of underwater conventional weapons and protection of ships and submarine. Numerical simulation of underwater explosions involves large deformation, the moving material interface and multi-media coupling. It has brought a lot of difficulties and challenges to the grid-based numerical algorithm. The material point method (MPM) is a meshfree method and takes the advantages of the both Euler and Lagrangian methods. Extension of the material point method to the numerical simulation of underwater explosion and the multi-medium coupling process was introduced. At last, spherical TNT underwater explosion in one-dimensional and TNT underwater explosion in two-dimensional were simulated. Blast wave produced by TNT exploding was computed. The spatial distribution and variation of the explosion flow field parameters were analysed. The calculated results are in good agreement with the results of AUTODYN, empirical formula of Cole and SPH, and provide a important reference to engineering applications.
