The University of Colorado Boulder centrifuge laboratory includes a 15 g-ton centrifuge, which has a symmetrical arm comprised of aluminum sections carrying swing-baskets at each end. The centrifuge is used for numerous research projects investigating the static and seismic performance of retaining structures and slopes, seepage mechanisms, contaminant transport, and offshore foundation structures. It can be used to simulate earthquake motions in flight by utilizing a servo-hydraulic shake-table.
The data acquisition system for the 400 g-ton centrifuge includes a NI PXI data acquisition system combined with a 12-slot SCXI chassis, with modules suitable for signal conditioning for LVDTs, strain-gauge-type sensors, accelerometers, and capacitance-type differential pressure transducers. Voltage control capabilities are also possible to operate solenoid and electronic flow valves. The 400 g-ton centrifuge includes 2 hydraulic rotary union lines which can be used to supply pressurized fluid to the centrifuge platform.
