Abstract

Bent shaft is the most common fault in rotating machinery. Bent shaft generates excessive vibration in a machine, depending on amount and location of the bend. In this paper, order analysis technique of vibration analysis used for bent shaft diagnosis is proposed. In order analysis, both phase and amplitude are obtained. From phase and amplitude, the fault type and location are usually identified. Experimental results show order analysis is an effective technique for bent shaft.
