ABSTRACT:
Horizontal vibration shakers21aand21bare disposed opposite to each other on both sides of a vibration table4, and either of the horizontal vibration shakers, e.g.21ais arranged vertically movable so as to produce a positional difference (offset) with respect to a horizontal vibration axis63of the other horizontal vibration shaker21b. When it is supposed that an accelerated velocity appears upwards on the left side of the vibration table4, while another accelerated velocity appears downwards on the right side of the vibration table4as a result of generation of a rotational mode M, one of the horizontal vibration shakers, e.g.21a, is elevated to produce the positional difference (offset) with respect to the horizontal vibration axis63of the other opposed horizontal vibration shaker21b. In addition, vibration forces of the horizontal vibration shakers21aand21bare controlled at the same time to produce a moment towards the reverse direction, whereby the rotational mode M is suppressed so as to balance the right and left moments.
