摘　　要：针对膛内高冲击高过载的恶劣环境以及对光、磁信号的屏蔽作用,使得弹丸旋转速度难以准确获取的问题,提出了基于弹载测试仪的高速旋转弹丸膛内转速测试方法。该方法利用弹载测试仪准确获取弹丸在膛内的轴向加速度信号,同时结合炮膛缠度和炮管口径信息,得出高速旋转弹丸在膛内整个过程的旋转速度。通过对实际测试数据分析表明,该方法能够准确测出旋转弹丸在膛内的转速,测试数据精度能够满足测试要求。Aiming at the problem of optical and magnetic signal shielding effect of the in-bore high impact overload,which makes the projectile rotation speed difficult to accurately obtain,an in-bore projectile speed test method based on high-speed rotating missile tester was proposed.The axial acceleration in-bore signal,at the same time was obtained,combining with the gun twist and barrel diameter information,the in-bore high speed rotating projectile in the whole process of rotating speed was concluded.The actual test data showed that the method could accurately measure the speed of the rotating projectile in-bore,precision could meet the test requirements.
