气动式爆炸冲击环境模拟装置模拟高量级冲击具有快捷、稳定的特点,通过试验研究表明其台面的重复性、均匀性及弹丸的速度控制都比较良好,能有效的模拟高量级冲击,从而取代了以往用火工品作为冲击源的试验技术,提高了其经济安全性。经过反复的试验调试,总结出了一些试验规律,同时利用有限元软件LS-DYNA进行了仿真分析,通过在仿真模型中修改模拟装置的各个参数,获取了这些参数对爆炸冲击环境变化的规律,从而为该装置的优化设计提供了有效依据。
The simulation of high-level impact by pneumatic explosive impact simulation device has the characteristics of quickness and stability. The experimental study shows that the repeatability, uniformity and the speed control of the projectile are relatively good, which can simulate high-level impact effectively Replaced with the previous use of explosives as a source of impact test technology to improve its economic security. After repeated test and commissioning, some experimental rules were summarized. At the same time, the finite element software LS-DYNA was used to carry out the simulation analysis. By changing the parameters of the simulation device in the simulation model, the rules of these parameters on the impact of the explosion impact environment were obtained, Which provides an effective basis for the optimal design of the device.
