This vibrator is a single-axis human-rated electro-hydraulic vibrator used to provide vertical oscillation.

It is capable of reproducing arbitrary time histories with peak-to-peak displacements up to 1 metre and peak accelerations up to 10 ms-2 and with frequency content from 0 to 50 Hz. The platform of the vertical vibrator is 1 m x 1.5 m.

The vibrator is used for fundamental and applied research in areas including human perception of vibration, postural stability, human body impedance, seat performance, and motion sickness.

The vibrator is also used for testing seats for cars, trucks, off-road machinery, rail vehicles, marine craft and aerospace environments according to current standards (e.g. ISO 7096, 78/764/EEC) or the specific requirements of the customer.
