So what if K1 = K2? You’ll find yourself with a division by 0… isn’t it?

HI Fabrizio, yes it is. However, due to the tyre rate being included, the equation for wheel centre rate is slightly different to that of the springs in series equation.

Thanks

Thanks a lot!

Hi,

The calculation process is to give you ideal spring rates to go testing on. You should follow the steps disregarding anti’s then go testing with that set up and tweak from there as the amount of anti’s required will alter with a brand new spring set up.

Thanks

I am a member of a formula student team and I was wondering about the ARB calculations. It seems like you have followed the Milliken books formulas in chapter “Ride and roll rates – 16.2 first example with more complete calculations”. Do you have a metric version of “16.5 Second example with simplified calculations” as well?

It would be very helpful!
Thanks, Nora Enderby
