Roll Damping Rates

[BenB]

Does anybody know a good number to start out with for roll damping ratios? On page 826 of RCVD it mentions a min of 3.655! That seems a little too overdamped to me.

I don't see any other places in the book that even talk about roll damping ratios so its hard to figure out why they put such a high number.

The suspension I am working on utilizes a 3rd spring/damper that only affects the ride rates so the other 2 dampers are for the roll. Here is an example on the Renualt F1 car:

I am working with a damper manufacturer to try and figure out how much damping force the roll dampers will need to produce.

Edit: I guess I don't know how to post an image so that picture of the Renault F1 car didn't show up.

The OptimumG Spring & Damper tech tips explain exactly how to come up with what you are asking for.

For some reason, the link on the OptimumG page is bad, so email me and I'll send copies. My email is in my public profile.

I would be curious to hear more about your design to seperate roll and ride damping. If your interested in talking about it, you can email me at Nomar116@ku.edu
