COMPARATIVE SPECTRUM ANALYSIS FOR VIBRATION IN A ROTATING MACHINE WITH MULTIPLE VARYING CONDITIONSFOR UNBALANCE FAULT AND CHECK FOR FREQUENCY PEAK DOMINANCE
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 2
Abstract
In the current research paper a comparative analysis has been done based on FFT and cross power spectrum analysis for effective diagnosis of vibration in a rotating shaft with different unbalance conditions. The shaft has been rotated at different speed with different unbalance masses to gather enough information regarding the vibration characteristics of the system. Amplitude spectrum showed noise interferences whereas the cross power spectrum was accurate in predicting the frequency peaks and its amplitude. Also frequency peak dominancy for unbalance fault was established for higher RPM irrespective of the presence of other types of faults.
