ANALYSIS OF VIBRATION IN ROTARY EQUIPMENT

Vibration is the study of the oscillatory motion of machines in a dynamic state and its measurement plays an important role in monitoring the machinery. Unbalance, looseness, misalignment and bearing defect are some of the causes of vibration. Our present study includes carrying out vibration analysis on the shaft bearing assembly and cone crusher using ansys software V16.0 and vibration analyzers. Cone crusher is an advanced high power hydraulic crusher in which heavy vibrations persist due to the eccentric sleeve. From the analysis carried out on crusher shaft root causes for vibrations have been identified and necessary modifications were made in the base frame thereby reducing the vibrations by approximately 20%. These results were confirmed by performing spectrum analysis on the base frame.
