引信加速度信号测试仪设计

Design of Fuse Acceleration Tester

为了准确获得引信在弹丸运动各个阶段的加速度信号,设计了一种可置于弹丸引信处的加速度测试仪,使用单片机和CPLD作为控制器,基于乒乓存储原理和负延迟理论,使得测试仪性能得到很大提高。通过靶场实验实测数据表明,测试仪能够成功获取引信发射及飞行过程的三轴加速度曲线,对于引信、弹丸和火炮的设计和研究具有重要意义。

In order to obtain the acceleration curve in each movement of the projectile accurately,an acceleration re-corder placed inside the projectile was designed;it used MCU and CPLD as controller and based on negative delay technique and the principle of ping-pong storage to improve its performance dramatically. The experimental testing data in shooting range showed that the tester can successfully obtain three-axis acceleration curve of fuse on projec-tile launch and flight process which had important significance for design and research of fuse,projectile and gun.
