STANDARDIZED MULTIAXIAL LOAD SEQUENCES FOR CAR WHEEL SUSPENSION COMPONENTS

STANDARDISIERTE MEHRAXIALE LASTBLAEUFE FUER BAUTEILE VON PKW RADAUFHAENGUNGEN

Standardized load-time histories have been used, since servohydraulic testing was introduced, to facilitate the comparison of the test results. Standardized uniaxial load sequences have been developed already for tests with fatigue-prone components of aircraft, helicopters, offshore-structures, wind turbines, rolling mill drives and car-wheel suspensions (CARLOS uniaxial). CARLOS multi is the first multiaxial standard for vertical, lateral, braking and longitudinal loads acting simultaneously on car front-wheel suspensions. It has been derived in cooperation with sixteen companies. The load-time histories are based on measurements with eight cars on public roads and the same operating profile which had also been agreed for CARLOS uniaxial. The load-time histories were generated with the help of the so-called guide function concept which guarantees the correct correlations between the four forces. By reducing the load histories to their fatigue-relevant contents the length of the return period of 40,000 km amounts to only approximately five hours. The standard load sequences are time histories with a constant sample rate and stored on PC streamer cartridges which are available on request from LBF.
