Method and device to filter the vibratory excitations between two pieces, in particular between the rotor and the fuselage of an helicopter.

摘要

- The present invention relates to a device for elastic linking between two parts (3, 5) to filter the vibratory excitations which are transmitted from one to the other, including: . at least one element for linking (7) between the said parts (3, 5) comprising a member (8) for transmitting the static force between the said parts (3, 5), and an actuator (9) associated with the said transmission member (8), . at least one means of measuring (10) a physical quantity representative of the said vibratory excitations, and capable of supplying first corresponding signals, and . electronic means for processing (12) the said first signals to convert them into second signals for control of the said actuator (9). - According to the invention, the said measuring means (10) is mounted on the said linking element (7). <IMAGE>
