80kN Shaker
The 80kN Shaker is an electrodynamic shaker complementary to the
large electrodynamic shakers, to carry out vibration tests on smaller test articles. The
facility consists of:
• One 80kN shaker used in vertical configuration for tests on very small test articles.
• One slip table to which the shaker is coupled in horizontal configuration for lateral
tests.
• One carbon fibre reinforced head expander to which the shaker is coupled in vertical
configuration for longitudinal tests.
The 80kN Shaker 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 100 g. A state-of-the-art
control system is available with up to 36 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.
