Effects of Interaction between Dual Shaking Tables

In conclusion, the interaction effects of the shaking table and specimen on the electrohydraulic servo-shaking table system are characterized by a peak-notch distortion in the amplitude-frequency response in a frequency band close to the natural frequency of the specimen.
