چکیده انگلیسی
This paper attempts to present numerical solution for the vibration analysis of a Flux Reversal Generator (FRG). A three-dimensional finite-element modal analysis (3-D FEA) methodology has been used for this purpose. Vibrations induced due to mechanical and unbalanced reasons have been analyzed. The 3-D modal analysis undertaken identifies the vibrations caused in every part of FRG (stator, shaft, end shields, bearings, and housing), which has been systematically documented. Modal frequencies and the respective speeds which are to be skipped immediately in order to operate the machine always in a safer acoustic zone have been identified and tabulated. To fine tune this, a harmonic analysis has been performed. Up to 10,000Â Hz has been considered and frequencies (and proportional speeds) such as 1500Â Hz, 1488.62Â Hz and 1568.78 have identified as the speeds to be avoided. Apart from frequently reported modal analysis on electrical machines, this 3-D vibration analysis for FRG considering every part of the machine will be helpful to examine the vibration in the machine as a whole. This forms the claim of the paper.
