线圈靶动态特性分析与补偿

Dynamic characteristic analysis and compensation of inductive coil

弹丸水下运行时弹道远不如空气中稳定,线圈靶作为其测速的区截装置如果半径太小,则容易捕捉不到信号或被弹丸打坏;半径太大其动态响应又相对太差。分析了线圈靶的动态特性,并给出了大半径线圈靶的补偿方法,试验证明:该方法可行。

In the water,the stability of flying bullet is not so good as which in the air,if the radius of inductive coil is too small,then the inductive signal maybe can not be received or the inductive coil maybe destroyed by bullet,whereas dynamic characteristic will greatly depress by too big radius of inductive coil.Dynamic characteristic of inductive coil is analyzed and compensating methods for big radius inductive coil are given,and these methods proved by tests are feasible.
