摘要

为了提高早期故障检测的准确性和有效性

提出了运用互相关去噪和构建混沌振子阵列

通过阵列扫描实现早期微弱故障的多个特征频率信号检测的方法.该方法将经过互相关去噪后的信号送入到混沌振子检测阵列中

让其作为混沌检测系统周期策动力的一部分

通过混沌检测系统相轨迹变化检测出表征同一微弱故障的多个频率信号.飞机转子系统早期碰擦故障检测为例验证了该方法的可行性.

Abstract

In order to improve the veracity and effectiveness of the early fault detection

the method of early detection method of weak fault signals with multi-character frequencies was proposed through array scan

by employing cross-correlation for denoising and building chaos oscillators array.In this method

the denoised signals were sent to the chaos oscillator detection array to act as a part of the chaos detection system's periodical driving force

and then the weak fault signals could be detected from the system's phase locus change.Its feasibility is verified by the example of an aircraft rotor system's early rub-impact fault detection.
