640kN QUAD Shaker
The QUAD shaker is the most powerful electrodynamic shaker of the ESTEC Test Centre. The QUAD shaker can efficiently and safely test payloads with a mass of up to 10000kg in vertical direction thanks to a thrust of 640kN generated by four single 160kN shakers. A magnesium alloy head expander connected to the four shakers creates a 3.3m x 3.3m interface for payload installation. The QUAD shaker is used for sine, random* or transient testing in the frequency range from 3Hz to 2000Hz with acceleration levels from 0.05 g up to 20 g. A state-of-the-art control system is available with up to 40 available channels for vibration input control and automatic test article response limiting. More acceleration measurement channels can be recorded by a mobile data handling system.
