The behavior of the system is investigated theoretically by usingthe mixed harmonic balance multiple scales method. Based on the obtained slow flow equations,a design procedure that maximize the dynamic range of the NES is presented. Singularity theoryis used to express conditions for the birth of detached resonance cure independently of the forcingfrequency. It is shown that the presence of a detached resonance curve is not necessarily detrimentalto the performance of the NES. Moreover, the detached resonce curve can be completely suppressedby adding nonlinear damping. The results of the design procedure are the compared to numericalsimulations.</p> |
