炮膛内高过载环境力测量系统设计

了获取弹丸在膛内高过载情况下的加速度信号，设计了一种弹载数据采集系统。选用高性能的Zynq 7000系列SoC芯片作为控制核心，将采集到的加速度信号通过A/D转换芯片送入大容量Nand Flash存储器完成数据的采集。通过对成品电路板的全面灌封技术，提高了系统整体的抗冲击能力。通过对实测结果进行分析，表明此系统可以准确地获取弹丸的膛内加速度变化曲线。

Design of high overload environmental force measurement system in gun

In order to obtain the acceleration signal of the projectile under high overload conditions in the bore, a missile borne data acquisition system was designed. The high performance Zynq 7000 series SoC chip is selected as the control core, which combines with the programmable A/D conversion chip and large capacity Nand Flash memory, to complete the data acquisition. Through the comprehensive potting technology of the finished circuit board, the overall impact resistance of the system is improved. Through the analysis of the measured results, it is shown that the system can accurately obtain the change curves of the acceleration of the projectile.
