The development of shaking table in China came relatively late [1, 3, 11 – 14].It can be roughly divided into four stages. In 1960s, the mechanical shaking table was the main stream with a working frequency of 1 Hz∼40 Hz, of which the characteristics of the specimens in low segment are difficult to be controlled [2, 10, 11].Electrohydraulic shaking table was then rapidly developed with its ...
A shaking table has a control unit for controlling the shaking table so that a target waveform signal is reproduced with at least an acceleration measuring signal as a feedback signal. The control unit is adapted for effecting control by employing the force applied to the shaking table from a specimen under test loaded on the shaking table as the feedback signal.
