摘要
简要介绍了枪弹在水中运动与空气中之特性差异 ,阐明了测定枪弹水中运动阻力的意义 ,基于软测量原理介绍了枪弹在水中运动时位移、时间数据对的获取方法 ,运用回归技术建立了弹丸在水中运动的位移——时间模型 ,依据动力学原理获取了枪弹在水中运动时的阻力及阻力加速度曲线 。
The difference of moving characteristics of bullet between underwater and in air is introduced in brief and the meaning for measuring resistance of moving bullet underwater is clarified.The method how to obtain the pair of data on displacement and time based on soft measurement is introduced.The model between time and displacement is set up by regression.Resistance and acceleration curve of moving bullet underwater can be gotten according to dynamics in order to give foundation for quantitative analysis and evaluation of capability of bullet.
