Induction motors and the generators ofen have problems associated with noise and vibration. Consequently,there is need for prediction of noise and vibration during the design of these machines.The Finite Element Modeling(FEM) method is used for the prediction and evaluation of natural frequencies and mode shapes of electrical equipment.However, FEM is ofen very difficalt,becouse of the influenc...

Today, machine tools play a vital role in the production of parts any manufacturing industry. The dimensional accuracy and surface finish work piece depends mainly on condition machine. Vibration occurring has been being serious problem for engineers many decades. Undesired relative vibrations between tool work-piece jeopardize quality surfaces during cutting.
 Many Condition Monitoring Te...

There is need to continuously monitor the conditions of complex, expensive and process-critical machinery in order to detect its incipient breakdown as well as to ensure its high performance and operating safety. Depending on the application, several techniques are available for monitoring the condition of a machine. Vibration monitoring of rotating machinery is considered in this paper so as d...
