Rotating Machinery for Condition Monitoring

Novelty detection has been developed into a state-of-the-art technique to detect abnormal behavior and trigger alarm for in-field machine maintenance. With built-up models of normality, it has been widely applied to several situations with normal supervising dataset such as shaft rotating speed and component temperature available meanwhile in the absence of fault information. However, the resea...

Understanding Amplitude and Phase in Rotating Machinery

The measurement of phase is essential in the balancing of singleor multi-plane balancing of rotating machinery. The rate of change of phase is important, as it may indicate the presence of a critical speed, and from the rate of change of phase one may be able to deduce the amplification factor or log decrement of a particular mode. Having a phase reference mark is particularly critical on compl...

International Glutamate Technical Committee

While sodium reduction in the diet is an important objective, when salt (NaCl) levels are reduced in foods, its palatability is also generally decreased. Monosodium glutamate (MSG) is a flavour enhancer that contains about 12% sodium, which is less than half of that contained in regular table salt at about 39%. Therefore, by the addition of an appropriate amount of MSG, the palatability of low ...

The Instantaneous Frequency Estimation In Rotating Machinery

Stages of run-up or run-down of rotating machinery are unstable random process. The methods of time-frequency analysis, such as short time Fourier transform, wavelet transform and so on, will be employed to analyze the relevant test signals. To obtain the laws of the instantaneous frequency of multi-component signals during the run-up or run-down periods, the method based on peak search is wide...
