MADYN 2000 has powerful analytical capabilities:

• Static analyses: Force, gear, weight loads, misalignment (the journal position in fluid film bearings is considered)
• Damped eigenvalues
• Harmonic response to unbalance, forces and moments, base excitation
• Transient response to forces and moments, base excitation; torques can be defined as a function of speed and speeds as a function of time for run up / down simulations. Nonlinear fluid film bearings can be considered.
• Parameter Variation: Undamped critical speed map, Campbell diagram, bearing stiffness and damping variation, coupling stiffness variation
