ENGDYN - bearing analysis

ENGDYN - bearing analysis

ENGDYN directly couples the crankshaft and cylinder-block dynamics with the bearing oil film to allow the user to perform a range of analyses to aid bearing design. ENGDYN incorporates a hierarchy of solution methods, from the industry standard mobility method through to more rigorous hydrodynamic (HD) and elastohydrodynamic (EHD) models. Whether early in a programme, when only concept-level models are available, or when detailed studies are required, ENGDYN provides the tools for the engineer to assess bearing performance.

Specific bearing applications

•    Bearing-type selection
•    Bearing durability
•    Friction and mass-flow calculations
•    Load transfer to powertrain

Key features

•    Direct coupling of crankshaft and crankcase dynamics with bearing
•    Mass-conserving hydrodynamic-lubrication modelling
•    Boundary lubrication modelling 
•    Thermal-balance modelling
•    Viscosity-pressure and viscosity-temperature dependence
•    Compressible flow to include effect of oil aeration
