Spoke Wheels and Hub Fatigue Test Procedures
This SAE Recommended Practice provides uniform laboratory procedures for fatigue testing of spoke wheels and hubs intended for normal highway use on trucks, buses, truck trailers, and multipurpose passenger vehicles. The hubs included have bolt circle diameters from 165.1 to 335.0 mm (6.50 to 13.19 in). It is up to each hum and/or spoke wheel developer to determine what test method, accelerated load factor and cycle life reuirements are applicable to obtain satisfactory service life in a given application. When deviations from the procedures recommended herein are made, it is the responsibility of th ehub and/or spoke wheel developer to modify other parameters to obtain parameters to obtainsatisfactory service life.
