Abstract

Abstract In this paper it is present a non contact method for 3D measurements on parabolic surface antenna. In order to obtain modal parameters and modal shapes of a parabolic surface antenna a Microflown USP (Ultimate Sound Probe) is used. Microflown sensors are close to antenna and can be used for the non contact measurement of the normal component of the structural velocity.
抛物面天线非接触式振动测量
提出了一种非接触式抛物面天线三维测量方法。为了获得抛物面天线的模态参数和模态振型,采用了微飞终极声探头。微飞传感器靠近天线,可用于结构速度法向分量的非接触测量。
