摘要
论述了如今流行的非平稳信号处理的方法的基本思路,指出分数阶傅立叶变换的独特之处。然后结合旋转机械故障诊断中一般均是采用双通道采集信息,利用全信息融合的方法提高诊断的正确率的情况。提出矢分数阶傅立叶变换的旋转机械故障诊断方法,并利用调频信号加以验证。
The basic way how to deal with the blame calm signal is discussed,pointing out the especially thought.Then technician always gather information with double channels in rotary mechanical failure and use full information amalgamation to increase the diagnostic validity. So put forward the way which is named Vector Fractional Fourier Transform to rotary mechanical failure and use LFM to validate it.
