摘要

弹丸穿越线圈靶时的姿态是影响线圈靶测速精度的重要因素。就弹丸姿态变化对线圈靶测速精度的影响进行了理论分析与建模研究

建立了与弹丸姿态相关的线圈感应电动势特性的理论模型。结合具体的参数

利用Matlab数值分析软件对高速运动的弹丸在入射线圈靶时的感应电动势随偏航角、俯仰角和偏移量的变化进行了数值计算

并经实验验证了模型的正确性。初步的研究结果表明:靶距为1 m时

弹丸姿态所引起的线圈靶测速误差可达0.511%

其中偏航角为主要影响因素。建模结果可为传感器的合理使用和误差补偿提供理论依据。

Abstract

In application of inductive-type coil target

its precision is influenced by the projectiles attitude. Study on the velocity measurement precision influenced by projectiles attitude

theoretical model of inductive-type coil target with different attitude is established

and calculate variation of induced electromotive force（ EMF） with different yaw angle

pitching angle and variation of offset using software Matlab. Then

the model is verified by experiments. The calculation results indicate that the error of projectiles attitude is up to 0. 511 % when the standoff distance is 1 m

and the yaw angle is more important. Modeling result can provides theoretical reference and advice for fair use and error compensation.
