摘要
针对目前诸如军事、铁路等领域事故爆炸仿真模型运算复杂、仿真效果较差的问题,提出了改进的仿真模型,该模型以粒子系统为基础,用定性、定量的随机变化模型代替爆炸物理过程的流体模型。将粒子发射速度参数与随机扰动速度参数相结合,建立通用仿真模型,通过给定不同的参数形成烟雾、火焰与爆炸碎片的具体仿真模型,可以有效降低爆炸效果模拟的计算复杂度。实验证明,该方法运算速度快,真实感强,可以满足各种爆炸效果的仿真需求。
To solve the problems of computational complexity of the explosion simulation models in military and railway accident fields,this paper proposed an improved simulation model which is based on the particle system and replaced fluid model by the qualitative and quantitative random changing model.Our simulation model was established by the combination of particle emission speed parameters and random perturbations speed parameters,and it can reduce the computational complexity of the explosion simulation effectively by giving different parameters and forming specific simulation models for smoke,fire and debris.Experiment shows that this method has good operation speed and perfect simulation effect,and can meet the needs of various explosive simulation effect.
