摘要
在水下弹丸的速度测量中 ,常采用线圈靶作为区截装置来测量弹丸的速度 ,但由这种方法只能得到位移时间曲线 ,要想得到位移速度曲线还必须拟合实验数据 ,文中介绍了三种速度拟合方法 。
The coil target is often used to measure the velocity of projectile, but the experiment data curve is displacement-time relation, it should be fitted to displacement-velocity relation. In this paper, three kinds of fit method are introduced and their error precision are analyzed with theory and experiment.
