Mathematical Analysis of Steady State Lateral Load Transfer on a Vehicle

This paper analyses lateral acceleration and steady state lateral load transfer on a vehicle during cornering. The three components of load transfer (un-sprung, kinematics and elastic) have been analyzed individually, Calculations and graphs/plots are made with PTC MathCad Prime 4.0. The paper covers effect of each components as a function of some other variables like lateral acceleration, roll center heights and varying roll stiffness. Un-sprung component provides the least opportunity to control the lateral load transfer while elastic component provides the maximum room for enhancing performance of the vehicle. Kinematic component can be altered through changes in the suspension geometry and weight distribution.
