Dynamical Performances of a Vibration Absorber for Continuous Structure considering Time-Delay Coupling

Figure 8

(a) is the amplitude of the master structure under different time delay as the frequency of excitation  rad/s and (b) is the square region in (a). For , the solid line is stability periodic motion by analysis via Harmonic Balance Method (HBM), and for , the solid line is obtained via Multiscale Method (MSM). The dashed line is unstable motion obtained by HBM and the dots are the results by numerical simulation.
