320kN Multishaker

The 320kN Multishaker efficiently and safely test payloads with a mass of up to 10000kg in horizontal direction thanks to a thrust of 320kN generated by two single 160kN shakers. A large light slip table connected to the two shakers creates a 3.5m x 3m interface for payload installation.

The 320kN Multishaker is used for sine-, random- and transient testing in the frequency range from 3Hz to 2000Hz with acceleration levels from 0.05 g up to 19 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 with up to 512 measurement channels.
