摘要
为评估破片式战斗部对典型反坦克火箭弹的拦截毁伤效果,进行了弹目交会、目标易损性分析,由此建立了毁伤判据。将目标离散成面元,基于射击线原理提出一种轴线夹角表示方法,进行破片精确落点参数计算。最后,联合毁伤判据和弹目交会模型构建出主动拦截战斗部拦截概率模型,并结合试验验证了拦截概率模型的有效性。试验结果表明:拦截半径为0.4 m、弹目交会距离在1.3~1.5 m时,战斗部有着较高的拦截概率,约为80%;试验所得拦截概率为80%,而模型预测拦截概率为73.2%,说明拦截概率模型能够较好地反映拦截交会与毁伤情况。
To evaluate the interception and damage effects of fragmentation artillery warhead against typical anti-tank rockets,projectile-target engagement and target vulnerability analysis were conducted.This led to the establishment of a damage criterion.The target was discretized into surface elements.Based on the shooting line principle,an axis-angle representation method was proposed to calculate precise impact point parameters of the fragments.Finally,an interception probability model for the active interception warhead was constructed by integrating the damage criterion with the projectile-target engagement model.And,the effectiveness of the interception probability model was validated through experiments.Experimental results indicate that with an interception radius of 0.4 m and a projectile-target engagement distance between 1.3 m and 1.5 m,the warhead has a high interception probability of approximately 80%.Experimental results show an interception probability of 80%,while the model predicts an interception probability of 73.2%,indicating that the interception probability model effectively reflects the interception engagement and damage situations.
