SAE J2562 pdf download.Biaxial Wheel Fatigue Test.
Th SAE Recommended Practice provides uniform Laboratory procedures for biaxial fatigue testing of wheels intended for normal highway use and temporary use on passenger car vehicles. The appendix provides a scaleable load file that is applicable to balasted passenger cars. Load files for unballasted passenger cars and light trucks will be added to this document.

3. DefInitions
3.1 Biaxial Test Machine
A machine for evaluating the fatigue life of the wheel under combined radial and lateral loads appbed to a rotating tire-wheel assembly through the tire.
3.2 Curb
A radially inward extension of the drum designed to contact the tire sidewall for reaction of lateral load. 33 Test Load Sequence
A series of Nock cyde reotal and lateral loads, tilt angles, wheel revolutions, and drum speed cory,at.ons that correlate to specific vehicle road load occurrences.
3.4 The Contact Patch Loads
Orthogonal radial, lateral and tore-aft wheel plane loads that act at the center of the Intert ace between the tire and road surtace.
3.5 Rated Wheel Load
Design load for wheel as specified by manufacturer equal to 1/2 the maximum static front axle load.
3.6 RadIal T.st Load
Radial load applied by test machine through the tire contact patch.
3.7 Lateral Test Load
Lateral load applied by test machine through the tire sidewal adjacent to the tire contact patch.
3.8 Radial Base Load
Radial wheel load that must be scaled tot vehicle application and design load.
3.9 Lateral Base Load
Lateral wheel load that must be scaled tot veiNcle application and design load.
3.10 flIt Angle
Wheel camber angle when inside biaxial test machine drum (inboard lateral loads use negative tilt angles).
3.11 Inboard Load
Lateral load vector acting at the tire contact patch toward the vehicle. This is the lateral load the tire- wheel assembly expeflences when it is on the outside of a turn.
3.12 Outboard Load
Lateral load v9ctor acting at the tire contact patch away trom the vehicle. This is the lateral load the tire- wheel assembly expeflences when it is on the inside of a turn.
3.13 Zero lateral load
Lateral load when the tire-wheel assembly is driven straight (no cornering or toe).
