【摘要】 轻型装甲车辆主动防护系统是近年来发展起来的新概念装甲防护手段,许多国家都在积极研究装甲主动防护系统。而对主动防护系统拦截效率的研究至关重要,本文通过对轻型装甲车辆主动防护系统拦截效率的研究,为主动防护系统的研制与使用提供了必要技术支持和理论参考。本文详细地阐述了轻型装甲车辆主动防护系统的工作原理,分析了系统的拦截能力。通过对主动防护系统拦截过程出现的误差进行分析,计算了这些误差引起的炸点偏差,建立了拦截误差模型;通过对拦截弹爆炸后破片的初速、飞行距离和时间、破片的角密度和单块破片杀伤概率的计算,确定了命中目标的有效破片数,建立了拦截弹杀伤概率模型,从而建立了主动防护系统拦截概率模型(该系统模型包括拦截误差模型和拦截弹杀伤概率模型)。采用蒙特卡洛方法,计算了轻型装甲车辆主动防护系统的拦截概率,并分析了误差对拦截概率的影响程度。结果表明:探测距离误差、引信作用时间误差、拦截弹速度误差、目标速度误差对拦截概率影响较大,射角误差、方位角误差、航路角误差和升降角误差对拦截概率的影响较小。更多还原

【Abstract】 Active protection system is a new defense concept for light armored vehicle, which has been researched and developed a lot by many countries. This paper focused on the research of interception efficiency of light armored vehicle, as a key issue in this field, providing theoretical reference and technical support for the R&D of active protection system.This paper introduced the principle of active protection system of light armored vehicle, and analyzed its interception capability. Based on the error analysis of interception process for calculating the bias of burst points, the interception error model was founded. The kill probability model of interception missile was established through the calculation of several mechanical properties of the fragments to determine the number of effective fragments, such as initial velocity, flight distance, fight time, angle density and the kill probability of single fragment. Thus the interception probability model of active protection system was established, which includes the interception error model and kill probability model of interception missile. By means of Monte Carlo method, the interception probability was calculated, and the error influence factor was also considered. The results show that the errors related to detection range, time delay of the fuse and the velocity of interception missile highlight the interception probability. By contraries, the errors involved with angle of fire, azimuth angle, fairway angle and lifting angle have a relative low influence to the interception probability.更多还原
