Excitations can be defined for supports which are connected to the rigid environment. The are considered in calculation of harmonic response.

ExcitationSupport

Several types of excitations can be considered:

A base excitations is a harmonic displacement or rotation of the node in the rigid environment. It has to be defined by giving a frequency. It could be used for vibrations of the grounding.

An excitation based on shaft rotation will rotate with the shaft. If can be used to model roundness errors. A factor for the harmonic is defined and a factor of one is an excitation with the shaft rotation speed.

An excitation based on inner ring rotation can be defined for rolling element bearings in case of rigid bearing rings. Here also a harmonic is defined and the excitation rotates with the inner ring.

An excitation based on outer ring rotation can be defined for rolling element bearings in case of rigid bearing rings. Here also a harmonic is defined and the excitation rotates with the outer ring.
