摘　　要：为提高磁感应线圈传感器测量弹丸高速运动的动态响应性能,研究了磁感应测速线圈系统特性与线圈几何参数之间的关系。根据正交试验设计的方法,基于Ansoft仿真软件,计算出不同几何参数下线圈特性的输出,并最终确定了一组用相对最优的线圈几何参数。实验测试结果表明:优化后的磁感应线圈提高了线圈输出的信噪比和输出灵敏度,有利于提高测速精度。To improve dynamic response performance of projectile high speed movement measure by magnetic induction coil sensors,relationship between magnetic induction speed measuring coil system characteristics and coil geometry parameters is studied.
