Translational Accelerate

Forced movement of a flange according to an acceleration signal

 Description The Translational Accelerate (or Accelerate) component generates a forced translational 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.
 Equations $a={a}_{\mathrm{ref}}=\stackrel{.}{v}$ $v=\stackrel{.}{s}$ $\mathbf{if}\mathrm{Use Support Flange}\mathbf{then}{f}_{\mathrm{support}}=-f$ $s={s}_{\mathrm{flange}}-\left\{\begin{array}{cc}{s}_{\mathrm{support}}& \mathrm{Use Support}\\ 0& \mathrm{otherwise}\end{array}$
