装备战斗损伤仿真中射线分析方法及其实现

装备战斗损伤仿真研究是BDAR中一项基础性研究内容,它对提高装备可靠性与维修性有着重要意义.战损仿真中射线分析环节的解决方法有碰撞检测法和解析法,目前有许多软件支持对几何模型的碰撞检测,但因为其算法复杂,运算量巨大,不适应于战斗损伤仿真的计算.该文介绍了战斗损伤仿真模型中破片场的生成与装备模型的简化描述过程,在此基础上利用解析的方法完成了破片对装备几何元素的射线分析,针对某型导弹发射车建立了损伤仿真模型.通过实验,证明了此算法的求解精度和运算速度都能很好地符合此战斗损伤仿真的要求.

The Method of Ray Analysis in Battle Damage Simulation of Equipment

The research of battle damage simulation is one of the basic contents in BDAR,and is of great importance to improve the reliability and maintenance of the equipment.The solutions of ray analysis include collision detection and analytic geometry.For now,many softwares support collision detection,but they can't be used in the simulation of battle damage because of the complexity and huge amount of calculation.This paper introduces a method to generate fragments field and to simplify the equipment model in the battle damage simulation model,and finishes ray analysis of fragments and equipment with the method of analytic geometry.Furthermore,a simulation model of battle damage for some missile equipment has been established,and the experimental results prove this method can effectively meet the requirements of precision and speed of calculation.
