【摘要】 由固定磁体感应弹速测试技术与数字化波形存储器、微机相结合组成的速度测量自动化系统,已在23mm口径二级轻气炮上应用成功。采用压缩磁场结构设计和严格的信号计时处理方法,使1～7.5km·s^-1范围的时间判读精度达到0.03％,整套系统的速度测量误差约0.1％,给二级轻气炮这类动高压设备提供了一种精确可靠的速度测试手段。更多还原

【Abstract】 A new system, which can measure the projectile velocity accurately, has recently been developed and successfully applied to a two stage light gas gun of 23mm in launch tube diameter. This system mainly consists of a magnetic induction part, a digital wave memory device and an automatic treatment system by personal computer. Accuracies in time observation and velocity measurement are 0. 03% and about 0. 10%,respectively,for the projectile velocity,from 1 to 6km/s. The high accuracy is due to the adoption of the techniques in compressed magnetic field designation and the over-zero time treatment of signals.更多还原
