Abstract

The topic of this work is the implementation of a coupled simulation method for the highly efficient computation of soft elasto-hydrodynamic lubrication (EHL) and abrasive wear progress in reciprocating hydraulic sealing systems. The mixed lubrication approach is based on the strong coupling of a non-linear finiteelement model for the seal geometry with the transient Reynolds equation. Based on this mixed lubrication approach wear simulations utilising an Arbitrary-Lagrangian-Eulerian algorithm can be performed. A rod seal model is used for the validation of the mixed lubrication approach. First, the hydrodynamic behaviour of the seal-rod interface and the mixed lubrication parameters are determined in Stribeck curve measurements on a tribometer. Finally, a comparison of optical measurements on a hydraulic test rig with simulation results of the rod seal shows the capability of the method for the computation and design of real sealing systems.
