Description

The Translational Speed (or Speed) component generates a forced translational speed according to an input signal,

The  boolean parameter determine how  is used:

When  is true,  is used as-is. The input signal must be differentiable.

When  is false (the default),  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 , 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.
