包络解调 meaning in Chinese
envelope demodulation
Examples
- Application of envelope demodulation method to fault diagnosis of spring invalidation
包络解调法在气阀弹簧失效故障诊断中的应用 - Application of wavelet envelope demodulation on early fault diagnosis of the rolling mill
小波包络解调在轧机故障早期诊断中的应用 - A new envelope demodulation method based on empirical mode decomposition ( emd ) is proposed to make up the limitation that meaningless frequencies often arise in the envelope spectrum of conventional envelope demodulation method
摘要提出了一种新的调制信号解调分析技术,来抑制传统的包络解调方法中经常出现的无意义的频率成分。 - The results of the experiment show that the peak value , rms , standard deviation , crest factor , kurtosis value and impulse value of the vibration signals can distinguish between the normal and abnormal conditions of the ball bearing when the level of noise is low
常用包络解调技术对此类信号进行分析,但易受噪声影响,使得齿轮或滚动轴承的故障特征难以凸显。本文从研究相关函数的特性入手,经理论证明,发现自相关函数并不改变调制信号的调制特征,但具有显著的降噪特点。 - By fuzzying these parameters and calculating the membership degree , fault characteristic vectors are designed and analyzed by gray relational degree ( grd ) , which could open a new way for fault classification and identification , including diesel vibration diagnosis by combining the ea and fuzzy method with the grd
对特征参数进行模糊处理和隶属度计算,在此基础上设计出故障特征向量,进行灰色关联度分析,从而把包络解调分析、模糊数学和灰色关联分析有机结合在一起,综合它们的优势,进行故障分类和识别,为机械设备的故障诊断提供一条新的思路。
