MADYN 2000 has unique modelling capabilities:

• Rotor-gear-bearing systems for torsional, lateral, axial and coupled analyses
• Bearing types:
  
  • Spring and damper,
  • fluid film bearings (fixed pads with any pad angles and centers of curvature, tilting pads with any pad angles, curvatures and support angles, hydrodynamic pockets, pressure dam),
  • floating ring bearings,
  • magnetic bearings
• Bearing supports with dynamic characteristics:
  • Spring damper mass systems,
  • general transfer funtions from measurements or FE analyses,
  • State Space Matrices, which can be provided by the user from other FE models,
    
  • coupling of supports and directions, respectively, by transfer functions
• Flexible couplings
• Fluid coefficients
• Elastic mounting of masses with an axial offset to their centre of gravity
• Superimposed shaft sections with different material, e.g. to model motor windings
• Consideration of notch factors for stress calculations
• Temperature-dependent materials
• Definition of standard, system-independent loads thanks to general denotations for locations
• Import of rotor data from ASCII files via a flexible interface
