27. Vibration Analysis of Rotating Machines: A Case Study

Vibration has been the most common challenges in the industries and machine for fatigue and before life failure. There may be many causes that arise as vibration. In this paper, common roots of vibration have been studied. The failure of machine is detected before failure, then some maintenance can be provided to machine to increase life cycle. Different industries contain the balancing problems, misalignment issues, and resonance, which we removed by balancing, alignment across coupling, and dynamic vibration absorbers. A case is presented of manufacturers and exporters of dyes and pigments, which is placed in Mahad, Maharashtra. The shaft that couple the hammer mill always keep rotating which produces the mechanical vibration. Present investigation studied the common causes that produce vibrations in rotating machines. Every machinery problem produces specific spectrum pattern, and these problems are identified with frequency and phase analysis. This paper explains in details about frequency analysis, phase analysis, unbalancing, and procedure of balancing. This paper presents the guideline for researcher to perform balancing the any rotary machine with effective way.
