Abstract

This paper deals with the study of whirling of shaft with three rotors. Natural frequency of the system is found by impact hammer test followed by identifying the speed at which whirling occurs in the system. Experimental results were verified by using Dunkerley's method for natural frequency. Rayleigh-Ritz equation is used to find out the critical speed of the shaft and hence to validate with experimental result.Keywords: Whirling, Natural frequency, Impact hammer, Dunkerley's, Rayleigh-RitzCite this ArticleRohit Tamrakar, Mittal N.
