Rotational Accelerate

Forced movement of a flange according to an acceleration signal

 Description The Rotational Accelerate (or Accelerate) component generates a forced rotational acceleration proportional to an input 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.
