一种基于激光跟踪仪的火箭撬滑轨主轨安装测量及其数据处理方法

A Method of Measuring and Data Processing of Main Rail Installation of Rocket Skid Rail Based on Laser Tracker

火箭撬滑轨是超音速飞行器试验中的核心设备,其建造的技术核心之一是百万分之一的轨道直线性相对精度,因此滑轨安装过程中的直线度精密测控及调整工艺对于使轨道安装至设计位置至关重要。因建设要求轨道测控精度在水平及竖直方向允许误差均为±0.2 mm,传统测量设备及测控方法较难满足其安装测量精度要求。本文提出了一种基于激光跟踪仪的火箭撬滑轨主轨安装测量及其数据处理方法,利用该方法成功对某火箭撬滑轨安装进行了精密测控,为今后类似工程提供一种新的技术思路。

The rocket skid rail is the core equipment in the supersonic vehicle test.One of the technical cores of its construction is the relative accuracy of one millionth of the linearity of the track.Therefore,the accuracy measurement and control of the straightness and the adjustment process during the installation of the rail are crucial at the design stage.Due to the construction requirements,the allowable error of track measurement and control accuracy in both the horizontal and vertical directions is±0.2 mm,and it is difficult for traditional measurement equipment and measurement and control methods to meet its installation measurement accuracy requirements.This paper proposes a laser tracker-based rocket skid rail installation measurement and data processing method and uses this method to successfully carry out accuracy measurement and control of the rocket skid rail installation,which provides a new technical idea for similar projects in the future.
