Abstract
A novel configuration of contact and friction models is outlined to describe friction in rough line contacts operating under mixed friction. The load distribution between fluid and solid body contacts is iteratively determined with a combination of the half-space theory and an established elasto-hydrodynamic model. On this basis, boundary friction and fluid friction are determined with a frictional work method and a fluid friction model, respectively. The calculation results based on the developed model are compared with experimental results achieved with rolling bearings, frictionally engaged freewheels as well as tribometers for contact pressures up to 2500 MPa. In wide ranges, experimental results show good compliance with the calculated results.
