The eigenvalue calculation can be used to identify critical operating states in the gearbox. To do this, eigenvalues are calculated from the masses and the linearized stiffness
in the overall system at the operating pointand compared with the excitation frequencies that occur.
The results of the calculation are eigenfrequencies and mode shapes of the entire transmission. The energy content of the different modes is analyzed in a post-processing step. The modes of vibration are divided into the categories: rotational, lateral, axial, or mixed.
The user is provided with a Campbell diagram for each gear level and an animation of the eigenmodes in the 3D model.
