Forced movement of a flange according to a reference speed
Modelica Standard Library
The Translational Speed (or Speed) component generates a forced translational speed according to an input signal, vref
The Exact boolean parameter determine how vref is used:
When Exact is true, vref is used as-is. The input signal must be differentiable.
When Exact is false (the default), vref is filtered and the derivative of the filtered curve is used to compute the reference acceleration of the flange. This derivative is not computed by numerical differentiation but rather by a first-order filter. The critical frequency (cut-off frequency) of the filter is defined by the parameter fcrit, which should be higher than the essential low frequencies in the signal.
The Use Support Flange boolean parameter enables a support flange on the housing. When true (checked) the support flange must be connected in the drawing. When false the component is internally fixed to ground.
if Use Support Flange then fsupport=−f

Conditional Support Flange
Real input; reference speed in ms
True (checked) means the reference position is treated exactly
Critical frequency of input signal when exact is set to false
Use Support Flange
True (checked) enables support flange
