Study of Physical Simulation Experiment of Penetration Fuze Layer-count Burst Point Control

针对硬目标侵彻引信实验室实物模拟实验,提出了利用多次冲击实验机对硬目标侵彻过程进行模拟实验方法的研究。介绍了硬目标侵彻引信的计层数策略,讨论利用冲击过程模拟侵彻过程加速度信号的可行性,设计了模拟实验系统并针对某型号侵彻引信进行计层数起爆模拟实验。通过与靶场试验曲线的对比,验证了该模拟实验方法的可行性,可较全面地检测引信起爆控制算法的准确性,以及引信活动部件动作的可靠性;但冲击峰值较低,冲击间隔较长,需要做进一步的研究和完善。

A method of using the repeated impact machine to simulate the process of hard target penetration is proposed for the physical simulation experiment of hard target penetration fuze. The layer-count algorithm of hard target penetration fuze is introduced. The feasibility of simulating the penetration acceleration signal by use of the impact process is discussed. A simulation experimental system is designed,and a layer-count detonating experiment is done using a certain type of penetration fuze. The result is compared with shooting range test curve,proving the feasibility of the simulation experimental methods. The accuracy of fuze burst point control method can be comprehensively tested. The reliability of fuze moving parts can be testified. Further research is needed as the shock acceleration peak is low and the shock interval is long.
