| 摘 要： | 激光靶测速是速度测量的一种重要的实验方法,其测试效率高、精度高、抗干扰能力强、测速范围大、受环境因素影响小,很有工程应用前景。针对激光靶速度的实际工程应用背景,深入、系统地研究了在匀加速阶段和匀速阶段测速时影响测速相对误差的因素,得出了在这两个典型阶段测速时,激光靶的安装位置及其精度与测速相对误差的重要关系。同时,分析得到了在给定测速相对误差前提下,激光靶的最佳安装间距。上述结果对激光靶测速的相关工程应用和相关实验的设计与开发具有重要的指导意义。

| Abstract: | Nowadays,velocity measurement is an important issue in the research,testing and experiment.Laser light target is a promising method of velocity measurement.The engineering installation method of the laser light target in the stages of uniform speed and uniform acceleration measurement is researched deeply and systematically,and the factors of affecting relative error in velocity measurement are discussed in details.The important relation between the installation position,the accuracy of the laser light target and the relative error of the velocity measurement in the stages of uniform speed and uniform acceleration is obtained.Meanwhile,the optimal installation spacing of the laser light target at the premise of the relative error of the velocity measurement is presented and analyzed.All the conclusions above have important guidance to both theory and application in engineering and laboratory of the laser light target. |
