高速机动目标毁伤试验替代技术可行性研究

Feasibility Study on Alternative Technology of High-speed Maneuvering Target Destruction Test

本文主要基于现阶段高速动目标毁伤试验验证手段的局限性,重点论证采用高速旋转试验手段模拟高速机动目标运动特性的可行性和正确性,从而支撑用旋转试验平台开展高速运动目标的毁伤机理的研究。首先,对旋转运动目标和直线运动目标分别开展侵彻效应仿真分析,验证了两种工况下弹丸剩余速度大小、弹丸的轴向位移变化和弹丸角度偏转情况变化的一致性,说明旋转运动目标替代直线运动目标的可行性。随后分别通过静态射击仿真与试验、动态射击仿真与试验相比较,进一步证明用旋转靶的切线速度等效直线运动动目标是合理的。通过这种模拟试验研究以及试验数据积累,可建立动目标的毁伤评估模型,形成一套完善的动目标毁伤评估模拟系统。

This paper mainly demonstrates the feasibility and correctness of using high-speed rotation test to simulate the motion characteristics of high-speed mobile targets,based on the limitations of the verification means of high-speed moving target damage test at the present stage,so as to support the research on the damage mechanism of high-speed moving targets with the rotating test platform.Firstly,the penetration effect simulation analysis is carried out for the rotating moving target and the linear moving target respectively,and the consistency of the residual velocity of the projectile,the axial displacement change of the projectile and the angular deflection change of the projectile under the two working conditions is verified,which shows that the rotating moving target is feasible to replace the linear moving target.Then,through the comparison of static shooting simulation and experiment,dynamic shooting simulation and experiment,it is further proved that it is reasonable to use the tangent velocity of rotating target to equivalent the moving target in a straight line.Through this simulation test research and test data accumulation,the damage evaluation model of moving targets can be established,and a perfect damage evaluation simulation system of moving targets can be formed.
