基于三维摄影测量的大型整流罩分离试验角点运动测量及分析

Measurement and Analysis of the Corner Motion of Large Scale Fairing Separation Based On Three-dimensional Photogrammetry

摘要:

作为一种先进的非接触光学测量方法，三维摄影测量技术已经充分证明了它是一种物体表面形貌和运动测量的实用有效的方法，已经应用于很多科研领域和工程应用中。本文利用三维摄影测量技术，在大型整流罩分离试验中，测量了整流罩角点在飞行中的运动位移-时间历程,并根据测量结果分析了整流罩运动规律及罩体“呼吸运动”对罩内有效载荷的影响。

Abstract:

Three-dimensional (3D) photogrammetry is an effective and practical tool for shape and motion measurement, which has been widely used in the field of experiment and research. This paper applies 3D photogrammetry to test the separation of a large scale fairing. The motion of fairing corner is obtained to analyze the kinetics of separation and the effect of “fairing breath”.
