Tribology Modeling Simulation
Tribology Modeling WHAT IS GT-3DMBD ADVANCED TRIBOLOGY?
GT-3DMBD Advanced Tribology is used to model the effect of surface deformation on conformal and counter-formal contact interfaces. Elasto-hydrodynamic (EHD) models are available to predict the behavior more accurately in the mixed lubrication regime.

Enhanced Tribology Solutions ELASTO-HYDRODYNAMIC MODELLING
EHD models can be applied to say crankshaft and connecting rod journal bearings, piston skirt to liner interface to address friction and wear issues. The functionality can also be extended to any journal bearing or piston-cylinder interface applications such as pumps, compressors and so on. Contact behavior at surfaces such as cams and rollers with complex crown shapes can be modelled using Contact Elasto-Hydrodynamic Lubrication (EHL) model to determine the contact pressure and subsurface stress.
