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 point and compared with the occurring excitation frequencies.
The results of the calculation are eigenfrequencies and mode shapes for the entire transmission. The energy content of the different modes is analyzed in a post-processing step. The modes of vibration are divided into categories: rotational, lateral, axial, or mixed.
The user is provided with a Campbell diagram for each gear stage and an animation of the eigenmodes in the 3D Model.
