Centrifuge shaking table

Update date: Aug 30

The shaking table system for geotechnical centrifuge, which can simulate sinusoidal and real seismic waves under a centrifugal force of 50 times earth gravity, is capable of providing significant data for the seismic design of structures

    Centrifuge shaking table tests on effect of vertical drain systems for liquefied soil. Abstract. It was observed that liquefaction induced by earthquake causes series damages to buildings and threatens the people and their properties. From the past studies, a number of countermeasures were proposed to reduce the build-up of excess pore water

    Jun 01, 2014 Centrifuge tests are known to better satisfy the law of similarity and are superior to 1-g shaking table tests from this aspect. However, it has been common in a number of previous studies, based upon both 1-g shaking table tests and centrifuge tests that the top 1/5 zone of a rock-fill dam exhibited a progressive failure

    The gold shaker table is a flow film separation equipment, that usually used to separate the gold particle grains from the ore material in the gold processing plant. Shaking table concentrator is developed from the early stationary and movable chute box, from percussion shaking table ( used in the coal mining industry) to the wilfley table and mineral processing eccentric rod shaker table

    If the centrifuge is wobbling or shaking, pull the plug. A little vibration is normal, but excessive amounts can mean danger. First, double check that the tubes are correctly balanced. If this does not resolve the issue, do not operate the centrifuge until it has been serviced by the manufacturer or dealer
