MESYS Calculation Software

If deformations of outer and inner ring are, for instance, known by means of FE analysis, they can be entered into the software to evaluate their influence on bearing life and contact stress by clicking on the all_img3-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 all_img89-button and any created table can be exported into a file using the all_img90-button.

In case of shaft calculations with 3D-elastic parts a shaft deformation can be transferred to the bearing calculation. In this case a check-box "Consider shaft deformations" is shown. If this check-box is cleared the shaft deformations are removed and not considered any more.

These deformations and deformations transferred from the shaft calculation are not considered in outputs for bearing clearance or the tolerance report. They only affect the calculation of load distribution and life.

In the current version, the definition of deformations cannot be used together with track roller calculation with elastic outer ring.
