Shaking Table Assembly Near Complete

Assembly of the Shaking table is nearly completed by attaching the driving megatorque motor next to the shaking table concrete base. The motor provides horizontal thrusts on shaking table. A new concrete base for the motor was built by FYP students, and the motor was placed on this new base to an exact height, in order to connect the motor driving shaft to the end of shaking table. As the shaking table is air-lifted, the horizontal thrust from the motor will provide ample energy to shake any objects horizontally on the table.

The power of shaking thrust will be examined next by first controlling the megatorque motor rotation, and a digital control system for the motor needs to be thoroughly checked. Also actual acceleration and frequency that can be achieved by the shaking table need to be measured by placing accelerometers on the table.


When the set-up of shaking table test apparatus is completed, the apparatus will be used to first determine the dynamic properties of residual soil. This apparatus has been used successfully to examine various dynamic responses of model ground at RCUSS, Kobe University, Japan and especially of examining the liquefaction problems as shown below.
