Delayed resonator with acceleration feedback ? Complete stability analysis by spectral methods and vibration absorber design
Original language description
This paper deals with the problem of active vibration suppression using the concept of delayed resonator (DR) absorber with acceleration feedback. A complete dynamic analysis of DR and its coupling with a single degree of freedom mechanical system are performed. Due to the presence of a delay in the acceleration feedback, the dynamics of the resonator itself, as well as the dynamics of combined system are of `neutral? character. On this system, spectral methods are applied to perform a complete stability analysis. Particularly, the method of cluster treatment of characteristic roots is used to determine stability boundaries in the space of the resonator parameters. Based on this analysis, a methodology to select the resonator parameters is proposed inorder to guarantee desirable suppression characteristics and to provide safe stability margins. An example case study is included to demonstrate these analytical results.
