Our projects include the technical measurement and analysis of vibration signatures of typical planetary gearboxes, focusing on observations of correlation between vibrations and micro geometric deviations within the planetary gear assembly. In addition to system identification, damage mechanisms and their propagation occurring in high-performance planetary gears are also in the scope of our research. In particular, the effects of re-ingestion of tooth fragments are considered.
