Fig. 1 ( a ) Classic DVA, ( b ) schematic model of the DVA with a lever, ( c ) base-excited primary structure, and ( d ) force-excited primary structure More

Fig. 2 ( a ) Comparisons between approximately (dashed) and exactly (solid) optimized AMF curves. The curve with circles denotes the frequency responses of the primary structure with no mounted DVA, ( b ) v o p t [ 2 ] versus v ~ o p t [ 2 ] , and ( c ... More

Fig. 3 Comparisons between the optimized AMF curves when ζ p > 0. Dashed curves with circles denote the case without DVA. Solid curves are with ( v o p t [ 1 ] , ζ a , o p t [ 1 ] ) and dashed ones are with ( v o p t [ 2 ] , ζ a... More

Fig. 4 The EO-AMF curves correspond to three different μL 2 values. Solid curves and circles represent the cases μ = 0.1 and μ = 0.2, respectively. Dash red curve denotes the frequency responses of the primary structure with no mounted DVA. (Color version online.) More

Fig. 5 The EO-AMF variations with respect to the deviated DVA parameters ( k a , c a ) from the optimal ones ( k a , o p t [ 1 ] , c a , o p t [ 1 ] ) : ( a ) The case where k a deviates and ( b ) The case where c a deviates. More
