What role for roll centres?
Q There is one thing that has been bugging me for some time now. And that is, just how do you prevent lateral migration of the roll centre?
The suspension with the higher KRC will have a lot less lateral migration, but that doesn’t mean its behaviour will be better or more consistent
A THE CONSULTANT
People who have read my material for any length of time will know that I don’t think the
‘kinematic roll centre’ (KRC), or front view force line intersection, actually is the roll centre in an independent suspension. That is, lateral force axis (road-vertical) acceleration, as in a banked turn or a dip or crest, and the KRC is offset laterally from the sprung mass c.g., that offset does not create a roll moment.
