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。
Laser target velocity measurement is an important experimental method of speed measurement. It has high testing efficiency, high precision, strong anti-interference ability, large measuring range and little influence by environmental factors. It is very promising in engineering application. According to the practical engineering application background of laser target velocity, the factors affecting the relative error of velocity measurement in uniform acceleration and velocity measurement are systematically studied. The relationship between laser target installation position Its accuracy and speed relative error of the important relationship. At the same time, the optimal installation distance of the laser target under the premise of the relative error of speed measurement is obtained. The above results have important guiding significance for the engineering application of laser target velocity measurement and the related experimental design and development.
