Rotating Shaft Stability Distribution in Entire Region of Equilibrium in Different-Shaped Bearings

Evaluating the rotating shaft stability in the bearing supporting the load applied when changing directions is a very laborious and costly task involving, for a start, the analysis of bearing oil film characteristics. We focused our study on the full-cylindrical, 2-lobe, offset-halves 4-tilting pad,...

Summary:Evaluating the rotating shaft stability in the bearing supporting the load applied when changing directions is a very laborious and costly task involving, for a start, the analysis of bearing oil film characteristics. We focused our study on the full-cylindrical, 2-lobe, offset-halves 4-tilting pad, and 5-tilting pad bearings currently in use most prevalently in industrial applications and studied the shafting stability in them. Consequently, we devised a new method capable of determining quantitatively the shafting natural frequency and damping ratio at any point of equilibrium in these typically shaped bearings.
