The invention is related to a landing gear vibration absorber (1) of a helicopter (2) with a landing gear (3) comprising a pair of skids (4, 5) and at least one cross tube (6, 7) for mounting the skids (4, 5) to a helicopter's fuselage (8). At least one spring-mass system (10, 20, 24) is mounted to the landing gear (3). Said at least one spring-mass system (10, 20, 24) is tuned to the helicopter's main excitation frequency and said at least one spring--mass system (10, 20, 24) being located at or near at least one antinode of the landing gear (3). The invention is related as well to a method of operating a landing gear vibration absorber (1) of a helicopter (2).

    Linvention concerne un amortisseur de vibrations de train datterrissage (1) dhélicoptère (2) dont le train datterrissage (3) comprend une paire de patins (4, 5) et au moins une traverse tubulaire (6, 7) permettant de fixer les patins (4, 5) au fuselage dun hélicoptère (8). Au moins un système masse à ressort (10, 20, 24) est fixé au train datterrissage (3). Ledit système masse à ressort (10, 20, 24) syntonise la principale fréquence dexcitation de lhélicoptère et le système masse à ressort (10, 20, 24) est situé sur ou à proximité dau moins un ventre du train datterrissage (3). Linvention concerne également une méthode de fonctionnement dudit amortisseur de vibrations de train datterrissage (1) dhélicoptère (2).
