摘要
为对舰船在战斗部外爆时破片和冲击波的毁伤进行快速评估,建立快速仿真算法。通过分析目标各部件和战斗部起爆点的相对位置关系,结合经验公式,计算舰船在战斗部外爆加载时的超压分布。模拟仿真战斗部外爆时的破片场,使用射击线方法,计算破片对舰船的侵彻毁伤。使用C++和glut库,实现仿真场景的三维漫游,给出有关的毁伤图像。
In order to fast evaluate the damage of naval vessel under air explosion, a simulation model was developed. By analyzing the relative location of warhead and the naval vessel and using empirical formula of blast wave, the peak pressure on the vessel under air blast loading was calculated. By simulating the fragment fields and using the THOR model, damage caused by the fragments was calculated. Compiling this visual simulation by Visual C＋＋ and glut database, the 3D scene roaming was realized, and the image of damage was obtained.
