Sources.Speed ​

Deprecated alias for VelocitySource.

Speed has been renamed to VelocitySource to align the Translational library naming with the Dyad mechanical libraries. This alias is retained so existing models keep working; use TranslationalComponents.Sources.VelocitySource in new models.

This component extends from TranslationalComponents.Sources.VelocitySource

Usage ​

TranslationalComponents.Sources.Speed()

Parameters: ​

NameDescriptionUnitsDefault value
ref_typeType of reference signal handling–Translation....Filtered()

Connectors ​

  • flange - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

  • support - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

  • v_ref - This connector represents a real signal as an input to a component (RealInput)

Variables ​

NameDescriptionUnits
sDistance between flange and support (= flange.s - support.s)m
vVelocity of flange with respect to supportm/s
aAcceleration of flange with respect to supportm/s2
