【摘要】 在对冲击信号特征详细分析的基础上,开发了一种小型、轻巧的硬目标侵彻动态参数记录仪,该记录仪通过装在轴线上的弹载加速度计来记录子弹加速度,借助一种新型的软防护技术,有可能使一枚高速飞行的测量炮弹减速而不损坏数据单元,并且测得了大于100,000g的轴向冲击加速度。更多还原

【Abstract】 Based on the study of the process of dynamic impact,a compact and lightweight flight data recorder (FDR) for penetrator testing has been developed. The FDR records the projectile acceleration with accelerometer in the body axis onboard. With a new soft recovery technique, it has been possible to decelerate a high-speed instrumented projectile without damaging the dada unit. Axial accelerations more than 100,000g at impact has been measured.更多还原
