Roll Center Load Transfer Calculator

Inputs

Axle load (m_a)

Static load carried by this axle.

Lateral acceleration (a_y)

Cornering acceleration in g.

Axle CG height (h_cg)

Effective center-of-gravity height for the axle load being screened.

Roll-center height (h_rc)

Roll-center height above ground. Negative values are allowed for below-ground roll centers.

Track width (t)

Distance between tire centerlines on this axle.

Method notes 2 notes

This first-pass axle model uses mass-equivalent loads and splits transfer by roll-center height versus remaining elastic roll moment arm.
Complete roll balance needs front/rear roll stiffness, tire load sensitivity, aero load, camber, anti-roll bars and suspension kinematics.
