Shaker table to calibration seismograph

Shaker table to calibration seismograph

A unique and simple shaker table (shake table or shaking table), designed, constructed, and installed at the Hawaii Institute of Geophysics, has proven to be a valuable aid in testing and calibrating short period seismometers, as well as ocean bottom and ocean sub-bottom seismometer/tilt meter packages. It consists of a platform suspended in a stairwell by a single elastic cord (10 m extended

    The shaker table was set to vibrate under a vertical harmonic motion of constant amplitude of 10 mm/s (0.4 in/s) and single frequency; vibrations in the horizontal plane were discarded to minimize tilt-induced errors (Hutt et al., 2009). The frequency of the input motion was varied from 2 to 256 Hz at intervals of 1/6 of octave in 43 tests

    Feb 01, 2017 Interestingly, although the calibration period of the seismographs is typically set at one year, the transmissibility of seismograph Sm+ at 5 mm/s (AM5) in summer of 2014 and 2015 are very similar. This unit was last calibrated in November 2013, so the low use of that seismograph during that period, less than 15 times, may be the reason of such
