Effects of operation parameters on the noise of the compound textured journal bearing are analyzed using computation fluid dynamic method and broadband noise source theory. After a three-dimensional model of the compound textured bearing is established, the lubrication performances of the bearing are compared under the isothermal and thermal situations. Further, the noise performances of the textured and smooth bearings are studied at the varied operation parameter. Numerical results show that appropriately decreasing the eccentricity ratio or rotational speed can reduce the noise of the compound textured bearing. Moreover, there is a critical length–diameter ratio of the bearing for suppressing the noise of the compound textured bearing. A part of the above conclusions is also verified experimentally.
