The wheel bearing calculation allows a calculation for wheel bearings with special inputs for the loading. The load is defined by inputs for the load on axis as mass 'ma', a wheel radius 'rW' and an offset from load position to bearing center 'δx'.
The default cycle is defined by a radial force factor 'fr', an axial force factor 'fa', a rotation speed 'n' and the number of rotations.
If the wheel is connected to the inner ring the load spectrum forces are defined as:
If the wheel is connected to the outer ring, the opposite sign is used.
The life factor 'fL' is defined as so it is a safety factor proportional to the load and 1.0 for 500h.
A graphic is shown for a variation of the axial offset and three axis loads to see the sensitivity of the results:
