Abstract
A method of reducing vibration in a structure comprising at least one rotor (101j) and a fixed set of sources of disturbance (102j) liable to give rise to disturbances in the fluid flow (11) that cause the rotor to vibrate, the method comprising a step of distributing the fixed sources of disturbance angularly in non-uniform manner so as to reduce the amplitude of excitation as seen by the rotor, and a step which consists in verifying that the maximum amplitude of a response of the rotor to the excitation is obtained by:
