here i am putting forward a topic related to control of excessive body
roll in SUVs(Sport Utility Vehicles). is there anyone who will give me
information regarding how anti roll bar helps to reduce the roll of a
vehicle? also how do we decide on anti roll bar stiffnesses and other
vehicle dynamics related issues while designing anti roll bar for a
vehicle that originally do not have any anti roll bar before?
The way to prevent excessive lean in an SUV is not to build the thing in the
first place. Up until a very few years ago, a high center of gravity was
anathema to designers. Now it's almost purely inexplicable fashion. A very
few SUVs trade back the high center of gravity with increased ground
clearance, but most don't.
Anti-roll bars (bafflingly also called roll bars) are used to do three
things: 1.) reduce overall body lean in a turn, 2.) reduce the response
time in a turning transient, and 3.) by adjusting the relative fore and aft
roll stiffness, set the balance (and to some extent, the turn-in dynamics)
between steady state oversteer (tail out) and understeer (plow).
Add at least a fourth for racecars - accomodate changes in track, driver,
and weather conditions. And maybe a fifth - having SOMETHING to change when
things aren't going well, and you're out of ideas.
We're l-o-o-o-n-g overdue for a swell of interest in lowrider SUVs. I
can hardly wait.
