Fatigue Life Analysis

In the context of fatigue life analysis, the fatigue life of gears can be determined under time-varying operating conditions, e.g. for vehicles and industrial applications. Load, temperature and speed spectra, which are determined from real operating conditions and modified for operation in the test rig, are used to investigate this fatigue life. In pulsators or back-to-back

gear test rigs with hydraulic load application the load can be varied during the operation according to these load spectra. Thus fatigue life investigations are possible. Load spectra tests can be run at the cylindrical, hypoid, worm gear test rigs as well as at the multidisc clutches and synchromesh systems.
