ADAMS/CAR ARB to Frame Displacement 1

[OTRace]

Hello,

I am just starting on using ADAMS/Car for my Formula SAE team and I'm using the standard model provided by MSC. I have modified our suspension hardpoints including the ARB and I'm trying to look at the forces and displacement of the ARB leaf link (or cantilever arm). Under PostProcessor, I see the request bgl_arb_to_frame_disp, I wanted to know what that means. The name tells me its ARB to Frame displacement but I want to know what point of the ARB and displacement relative to what point of the Frame. I am using a U-bar type ARB in the model as shown in image attached.

Thanks!

Typically the arb is mounted in rubber D blocks. The only logical meaning of this request that I can think of is that it is the deflection of the D block. Try increasing the stiffness of the D block to see if it reduces. Typical D block rate is 2000-6000 N/mm, anything more than that and it is stiffer than the frame.
