Model Fidelity Reduction - Anti-Roll Bar

Setup → Model Simplification → Anti-Roll Bars

Converts the Beam or FE-Part modelled Adams Car Anti-Roll Bar component to the Simple Anti-Roll Bar (two rigid parts connected via a revolute joint and a torsional spring) to reduce simulation times.

For the option:	Do the following:
Select Anti-Roll Bar
Anti-Roll Bar	Select the Adams Car anti-roll bar component (Beam of FE-Part method) that you want to convert to the simplified anti-roll bar to make simulations faster. Important: Only the Adams Car anti-roll bar component is supported.
Define Test
Bump Travel	Specify the maximum vertical input that is applied to the Anti-Roll Bar on one side while computing the equivalent torsional stiffness that is used for modelling of the simplified anti-roll bar.
Rebound Travel	Specify the minimum vertical input that is applied to the Anti-Roll Bar on one side while computing the equivalent torsional stiffness that is used for modelling of the simplified anti-roll bar.
Compute Equivalent Stiffness	Select to start the computation of the equivalent torsional stiffness used for modeling of the simplified anti-roll bar. Once the simulations are finished, the equivalent stiffness is shown in the gray field. You need to click this button before the page 3 is enabled.
Choose Reduction
Derived Stiffness	This field shows the computed equivalent stiffness from page 2 and cannot be changed. It is used for reference only.
Stiffness to Apply	Specify the rotational stiffness of the simplified anti-roll bar component that is used when replacing the (Beam or FE-Part) anti-roll bar in your assembly by the simplified anti-roll bar. The default value is set to the computed equivalent stiffness.
Plot	Select to regenerate the Force-Deflection curves for the simplified anti-roll bar utilizing the Stiffness to Apply value for the rotational stiffness. The Original curve is the characteristic for the base anti-roll bar model in your assembly. The Simplified curve is the characteristic for the simple anti-roll bar model.
