Dynamics of machines

Rotor dynamic analysis

·         calculation of bending (whirling) vibration of rotors and rotor systems supported in rolling or sliding bearings

·         estimation of eigenfrequencies, vibration modes and critical speeds

·         determination of the system stability limit

·         determination of the system damping at critical speeds

·         estimation of operational safety

·         calculation of the system response in operation speed range for unbalance excitation /forced vibration

·         optimization of bearing support with regard to position of critical speeds and stability
