Patent ID: 6954686

Claim:
A method of tuning a vibration absorber to a reference driving frequency, said absorber comprising a damper block secured to a support having one end mounted in fixed manner in a structure, the method comprising: a measurement step for estimating the offset between the tuned frequency of said absorber and the driving frequency so as to produce a reference value; and an adjustment step for adjusting at least one adjustment value of said absorber to said reference value; wherein said measurement step comprises: establishing an estimated transfer function for said absorber over a frequency band extending on either side of said driving frequency, on the basis of a first series of measurements of the acceleration at the mount in the structure, and on the basis of a second series of measurements of acceleration at said damper block; defining a theoretical transfer function for said absorber, which function is parameterized by said tuned frequency; minimizing the difference between said estimated transfer function and theoretical transfer function in order to obtain said tuned frequency; and defining said reference value by means of said tuned frequency.
