Calculation of rotor-bearing systems
In turbomachinery, there is a complex interaction between the rotor and the bearings. Due to the specific lubricating film properties, plain bearings can exhibit a strong non-linearity with regard to the bearing forces and be the cause of self-excited vibrations. For a safe bearing design, the calculation models must therefore take the rotor and housing vibrations into account. The RotorFEM rotor dynamics program is optimally designed for coupling with the COMBROS R/A plain bearing calculation programs.
The scope of calculation covers both linear and non-linear analysis methods, allowing the natural and forced vibration behavior of the rotor-bearing system to be simulated. All common characteristic value diagrams such as critical speed maps, Bode diagrams or Campbell diagrams are created.
