Abstract:In the case of the journal-bearing system under a mixed or boundary lubrication regime, the deformation of the bearing, the flow of the lubricating medium, and the contact of the asperities should be taken into account. The lubrication problem at the journal-shaft interface is a complicated fluid–solid coupling problem. In this study, a new approach is proposed to analyze the dynamic fluid–solid coupling problem of journal bearings. The dynamic fluid–solid coupling problem is solved by the presented non-linear… Show more
