This is the servo-hydraulic shaking table upon which the model containers are mounted. For a rigid shaking mass of 2700 kg (model plus container) and a hydraulic pressure of 24 MPa, the actuators have the capacity to produce between 14 and 30 g shaking accelerations at frequencies up to 200 Hz. The maximum absolute shaking velocity is about 1 m/s and the stroke is 2.5 cm peak to peak. Two pairs of single acting actuators, one on each side of the container, provide a net peak actuator force of 400 kN.
