| Abstract | ||||
| A theoretical analysis is presented to predict the dynamic performance characteristics of a circular thrust bearing with a central recess and integrated with a restrictor of finite fluidic resistance. The gmerning equations of flow are solved in closed forms to obtain pressure distribu-tions in the bearing clearances. Assuming a sinusoidal variation in the oil film thickness, the damping load, flow rate and damping coefficient are evaluated for squeezed disks, Results are presented in dimensionless terms describing the cyclic variation of the different squeeze parameters and the different geometrical aspects. They show the non-linearities of these parameters especially at high amplitude ratios. | ||||
