Development of a Biaxial Fatigue Load File to Emulate the Services Demanded of a Motor Sport Vehicle 2012-01-0798

A wheel load history was provided for front and rear positions of a sport car under service that included motorsport track and public road service. Biaxial load files are developed from the wheel load histories. A wheel load history is the combination of cycles and respective load pairs whose sum is the expected life of the vehicle. An alternate process to SAE J2562 is used to reduce wheel load history to a biaxial load file with equivalent fatigue damage. The contents of the load file were used to calculate life prediction using finite element and fatigue analyses. Wheels were then tested on the biaxial test machine to establish correlation with simulation predictions. Since the wheel designs are unique between front and rear positions, the biaxial fatigue files are developed and maintained similarly unique to position. Correlation between simulation prediction and biaxial fatigue tests has been confirmed.
