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

Blasting seismographs: Transfer functions, standards and

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
Measurement of Blast-Induced Ground

ment seismographs and calibration tables were designed by the Bureau as part of an extensive research program conducted from 1930 to 1940 to study the effects of ground vibrations from quarry blasting (25). This study proposed that acceleration, calculated from
Vibration Shaker Horizontal Table | Excitation | The Modal

The Horizontal Table has a 6 x 7.5 inch (15 x 19 cm) platform and can operate both horizontally and vertically. The Table is carefully designed to remove any side loading from the shaker suspension and comes with pre-drilled inserts to facilitate easy test subject attachment. The Horizontal Table is available in a Kit with the 2075E and 2110E
Coupling of blasting seismographs to rock and its

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

Improvements in Accelerometer Calibration Using Fringe

A flat mirror is mounted on the shaker table located on the right side of the moving element, opposite the table upon which the accelerometer is mounted. This shaker design allows optical access to the shaker mounting tables through a center hole in the magnet (bottom photo in Figure 1). This shaker system was described by Payne and Steffen [2
How to Calibrate an Accelerometer | Brüel & Kjær

Simple Calibrator for Accelerometers. The most convenient means of performing a periodic calibration check is by using a B&K battery-powered calibrated vibration source. This has a small built-in shaker table which generates precisely 10 m/s 2 at 159.15 Hz. The sensitivity calibration of an accelerometer is checked by fastening it to the shaker
