The Stability Analysis of Hydrodynamic Journal Bearings Allowing for Manufacturing Tolerances. Part Ⅱ: Stability Analysis Model with Consideration of Tolerances

摘要：

This paper extends the analysis of Part Ⅰ to investigate the influences of the manufacturing tolerances on the stability of the journal bearing system. A new dimensionless stability map with consideration of the manufacturing tolerances is modeled by introducing in the concepts of nominal dimensions and limits. Several new parameters are deduced to express the synthesized manufacturing tolerances and the structural parameters of the journal bearing system based on a new dimensionless modified Sommerfeld number. The work also shows that the journal bearing system is insensitive to the manufacturing tolerances when the system eccentricity ratio runs around 0.30.4.
