磁强计测高自旋弹丸转速的方法及应用
Method and Application of Rotational Speed Test of High Spinning Projectile Based on Magnetometer
摘要
Abstract
Based on the principles of mechanics,the output signal formula of magnetometer was studied in this paper in the case of general movement of the projectile.Then in the case of high-spinning environment,based on reasonable assumptions,the output signal formula of the magnetometer was simplified.And based on the simplified formula,the determination of the half-cycle was studied,and the test method of rotational speed of projectile was studied.The rotational speed curve obtained by the method in this paper is almost same as that obtained by the gyros in the same live-fire test,the result indicates the effectiveness of the method.关键词
