摘要
本文利用振动信号实部与虚部之间Hilbert关系的原理,发展了它在模态试验中非线性检测技术。针对工程结构的特性采用了快速算法和修正技术。
In this paper,based on the principle of Hilbert connection for real and imaginary part of vibration signals,the inspecting technique for nonlinear vibration was developed.In accordance with the special characteristics of engineering structure,a sort of fast algorithm and correction technique was used.By application in a fairing of rocket,it was proved practicable.
