Hello. In order to study for an exam, I would be very grateful if you answered these questions. Thank you so much in advance.
Hello. In order to study for an exam, I would be very grateful if you answered these questions.Thank you so much in advance.(a) Imbalance, misalignment and looseness faults all produce peak value of vibration at frequency of 1x rotating speed. What characteristics of these faults enable us to differentiate between them?(b) During monitoring, both mechanical faults and electrical faults will affect the vibration signal. Suggest an action to be taken to differentiate these faults.(c) The spectrum of a vibration signal only indicates peak amplitude at Zero frequency, dominating the other components. What is the likely cause and how could it be remedied?(d) In the Cepstrum of a vibration signal [obtained from Spectrum] a peak value is shown at time 0.02 seconds. Identify the likely source.
