Lateral Load Transfer Parameters and Calculation of Anti-Roll Bar Stiffness, Auxiliary Roll Stiffness with 4-FWD Passenger Vehicle Suspension Data

Please note:

Front Ride Rate: 200 lb/in

Rear Ride Rate: 250 lb/in

1,Calculate the following parameters:

(i) Roll moment (ft-lb/g)

(ii) Roll gradient (deg/g)

(iii) Load transfer due to roll or elastic component (lb/g)

(iv) Front roll stiffness (ft-lb/deg) at wheel center level (hint: isolate the tire contribution)

(v) Front anti-roll spring rate (lb/in) for one wheel jounce

(vi) Front anti-roll spring rate (lb/in) for roll

( vii) Front anti-roll bar stiffness (ft-lb/deg)

(viii) Auxiliary roll stiffness (%)
