摘　　要：根据核爆炸的基本表现过程,建立了一个综合的爆炸模型,可以实现实时的核爆炸景象模拟。通过球形扩张建立冲击波的冲击模型,并实现了快速的碰撞检测;使用视角范围内的粒子抛撒,表现核爆炸产生的飞溅物;利用适当简化后的Navier-Stokes方程,优化求解策略,实现具有复杂运动形式的蘑菇状烟云模拟。实验结果表明,采用该模型可以实现实时的核爆炸效果模拟,通过控制和调整参量,可以获得多种不同类型的核爆炸效果。Based on real nuclear explosions, a comprehensive explosion model is developed, which can achieve realtime simulation of nuclear explosion. Spherical expansion is adopted to express the shock wave, Additionally, fast collision de tection is realized. The splash of the nuclear explosion is represented by using particle dispersion within the view range. The NavierStokes equations are simplified and solution strategies are optimized. Furthermore, the mushroom is realized with complex forms motion. Experimental results show that using the model can achieve a realtime simulation of the effects of a nuclear explosion. By controlling and adjusting the parameters, many different types of nuclear explosion effects can be obtained.
