A shaker table (10) includes a table base (12) mounted upon isolating supports (32) and vibrated by vibrators (34, 36). The vibration is conveyed through and damped in a flexure member (16) comprising pairs (26, 28) of honeycomb layers (18, 20, 22, 24) joined and bonded together by sheets (42) utilizing beads of elastomeric adhesive which space the honeycomb layers apart. A segmented top plate (14) is secured to the topmost honeycomb layer and is divided into a plurality of sections or segments (68-82) for separate resonances. In this way, highly damped vibrational resonances of table top plate (14) are obtained.
