Roll play with a Rotax racer
Q Soon I will be designing an F500 car, and I have questions regarding their suspension. Above is a picture of a typical rear end; it seems to show two Panhard-like rods attached to a pivoting frame. The frame is hinged on both sides. At first I thought this set-up does not seem to allow any roll, other than that given by flexing of that frame. This may be part of the design intent, as the rules prohibit anti-roll bars. How do you determine the roll centre for this design? For F500 racecars, would there be an advantage to a low rear roll centre as found with the Mumford link?
I think they would have a tendency toward locked axle understeer,
