Application of Artificial Neural Networks to Calculation of Oil Film Reaction Forces and Dynamics of Rotors on Journal Bearings

Figure 8

Cascade frequency response during deceleration of the rotor from 3900 rpm down to 1000 rpm during 32 sec., calculated using the trajectory approach (a), neural network approach (b), and comparative results of the housing’s vibration measurement and the rotor’s vibration calculation (c).
