摘　　要：为解决蒙特卡洛仿真法评估导弹毁伤效能计算时间长、效率低的问题,研究了一种基于MATLAB的导弹毁伤效能仿真计算效率优化方法。在建立一体化目标易损性模型和战斗部威力场模型的基础上,应用包围球相交检测法实现破片射击线与目标部件相交的快速检测,并建立了交点求解优化算法;基于MATLAB编制了导弹毁伤效能快速数值计算程序。实例结果表明:与常规线面相交求解算法相比,优化方法的计算效率提高了约16倍。During the evaluation of missile damage effectiveness,Monte Carlo simulation computation was usually time consuming and of low efficiency.To optimize the computational efficiency of damage effectiveness simulation,the MATLAB was introduced.First,an integrated target vulnerability model and a warhead power field model were constructed.Based on the two model,the bounding sphere intersection detection method was applied to realize the fast detection of the intersection between fragment shooting line and target components.Accordingly,an optimized way of calculating the intersection point coordinates was developed.Furthermore,a fast numerical computation procedure for missile damage effectiveness was programmed based on MATLAB.Moreover,a practical computation was conducted.Results showed that compared to the conventional line-surface intersection solution algorithm,the computation efficiency was increased by about 16 times after optimization.
