基于三维摄像测量法的整流罩分离运动规律测试与分析

Test and analysis of the motion law of fairing separation based on three-dimensional photogrammetry

整流罩分离是火箭飞行过程中重要的动作,能否实现安全分离是决定发射成败的关键因素之一。采用三维摄像测量方法,对大型弹性整流罩分离过程进行了运动测试,通过测试结果来分析整流罩在分离过程中质心的运动规律及罩体结构"呼吸运动"对罩内有效载荷可用空间的影响,以及研究弹性变形对分离过程及分离系统设计的影响。

Fairing separation is important action in the rockefs flight, can achieve safe separation is decidedto launch success or failure, which is one of the key factors. This paper adopts three-dimensionalphotogrammetry method to test the large elastic fairing separation process. According to the results toanalyze the motion rules of the center of mass of test article in separation process, and the effect of theavailable space of the pay load in structure for the , and studying on the influence of elastic deformation onthe separation process and system design.
