Abstract

Torsional vibration in the statically loaded ball bearings employed in satellites can be a source of navigational error. To analyze these vibrations it is necessary to know the lateral compliance at the bearing contacts. This paper describes and illustrates a simulation approach to the determination of the relationship between tangential force and the tangential displacement at the interface of contacting rough surfaces in the presence of coulomb friction acting at the microcontacts formed by surface asperities. 1 Introduction In this paper we consider the contact of two parallel flat rough surfaces pressed together so that the total load supported at the mating high spots divided by the apparent area over which contact takes place (the macro-contact area) equilibrates the pressure p which is forcing the su
