This element allows the user to consider harmonic loads (moments or forces) on a shaft according to: . In case that the frequency is not the same as the one corresponding to the shaft speed, then it can be manually specified by checking the box next to the "Frequency" at the software dialog. A phase shift can be defined for the force as well.
The dynamic force will only affect the results for the harmonic response. Bearing life, contact stress or safety factors for shaft strength will not change.
