If deformations of outer and inner ring are, for instance, known by means of FE analyses, they can be entered into the software to evaluate their influence on bearing life and contact stress by clicking on the -button behind both diameter input fields.
They are two possibilities. On one hand, with the option ‘Point data’, as many points of deformation as needed can be added to the data table. Any point is positioned circumferentially by its angle and both the axial and radial deformation can be defined. Note that the deformations along the rings between any defined points will be linearly interpolated. On the other hand, there is an option to define an approximate deformation curve by ‘Fourier coefficients’ as shown in the picture below. Additionally, a whole table can be imported from a csv-file using the -button and any created table can be exported into a file using the -button.
In the current version, the definition of deformation cannot be used together with track roller calculation with elastic outer ring.
