EFFECTS OF TEST SPEED AND SURFACE CURVATURE ON CORNERING PROPERTIES OF TIRES

The effect of test speed and surface curvature on tire force and moment properties has been investigated. Lateral force at low slip angles increases linearly 8 to 9 percent for a tenfold increase in test speed. The effect of test speed on tire force and moment properties produces only a modest change in predicted steady state vehicle handling, but a rather significant change in predicted transient vehicle handling. Surface curvature tends to reduce slip and camber generated lateral force and aligning torque, but the effect is extremely complex and no simple flat to curved surface transformation relationship exist. /GMRL/
