本文通过对线圈靶产生的信号的分析,对用线圈靶测定弹丸速度时产生误差的原因和提高线圈靶精度的措施进行了探讨,并利用小直径感应线圈靶对5 6式7.62mm步枪进行实验获得良好的效果。由实验证明了小直径感应线圈靶能够达到鉴定级称准,初步认为能够用来鉴定其他各种靶圈的精度。 本文并对DCS-451型电子测时仪利用线圈靶测速时可能存在的误差进行分析,提出了改进措施,实验结果证明达到了予期的效果。
In this paper, by analyzing the signals generated by the coil targets, the causes of the errors in the determination of the projectile velocity by the coil targets and the measures to improve the accuracy of the coil targets are discussed. Experiments on the 5.6-type 7.62mm rifle with small diameter induction coils Get good results. Experiments show that the small diameter induction coil target can reach the identification level, initially considered to be able to identify the accuracy of various other target rings. In this paper, the error that the DCS-451 electronic time-measuring instrument may use when using the coil target speed is analyzed, and the improvement measures are put forward. The experimental results prove that the expected effect is achieved.
