R-201/202 RESEARCH/EDUCATIONAL SHAKE TABLES

The ANCO R-201/202 earthquake shake tables are a 1 DOF and 2 DOF economical research and teaching tool for earthquake engineering, vibration, system dynamics, control systems, and data acquisition and processing studies and demonstrations.

Portable, total weight <90/160 kg (R-201/R-202), no anchorage required
Table top: 50x75 cm (R-201) or 60x60 cm (R-202) with tapped hole grid
Achieves 1.5 g acceleration with an 80 kg payload
Peak displacement of +/- 12 cm
Peak velocity of 50 cm/s
Frequency range of operation 0 to greater than 20 Hz
Can also be used as a large structure vibrator with 1.2 kN force
Uses all electric roller screw actuator
Requires single phase 3/6 kW (R-201/R-202) power
Allows for one passenger riding to experience earthquake motions such as at science parks and museums
Includes ANCO SPECTIME program for user generation of spectrum compatible earthquake time histories
Provided with either of two digital controllers:

Economical open loop ANCO FOX TROT hand held controller with library of preprogramed and user supplied earthquake drive signals

Powerful closed loop ANCO PC based DANCE equalizing controller with 16 channels data acquisition, earthquake library, SINE sweeps

ROLLER SCREW DRIVES accept a +/- 1 V drive signal corresponding to +/- 100% displacement. This drive signal can be provided by FOX TROT, DANCE, or a user supplied signal source. Roller screws use an electric servo motor with internal encoder and digital PID servo loop to drive the roller screw under displacement command. The frequency response exceeds 20 Hz depending on the table mass loading.
FOX TROT is a hand held open loop controller that provides one or two channels of displacement drive signals to the roller screw drive (s). This controller uses an MP3 format file and a program is included that allows the user to convert external real or generated earthquake drive motions (or other wave forms) into the MP3 format and download them into FOX TROT. The program can also double integrate the user drive signals to get a displacement drive from acceleration data. A manual adjustment of the output signal amplitude allows the user to scale the table drive from 0%-100%. As an open loop controller FOX TROT does not use a table feedback accelerometer and has good fidelity in reproducing drive time histories.
DANCE is a 1 or 2 DOF PC based closed loop controller and uses feedback from a table accelerometer, thereby providing improved table fidelity.
(See http://www.ancoengineers.com/AncoPrograms/Brochure/Dance.pdf )
DANCE performs an equalization process using the table feedback accelerometer to improve fidelity and record the actual table response as well as a total of 16 channels of transducer data. All data can be displayed (time histories, FFT, Response Spectra) and also exported for use by other programs. The PC and feedback accelerometer and power supply are included.

SPECTIME is a program that allows the user to enter the break points of a Required Response Spectrum (RRS) and then computes a time history with a similar RRS. This time history(s) can them be imported to FOX TROT or DANCE to drive the shake table.

OPTIONAL EQUIPMENT:
Additional accelerometers and ICP power supplies
Anti-Aliasing filters
T bar table attachment or seat attachment for passenger stability
