Finite
Element Methods Analysis
By
means of FEM-calculation we conduct tension- deformation-
and modal analyses for various components. Modal analyses
in particular play a key role in the testing industry, because
the natural frequency of the component and the testing frequency
must not interfere.
Vibrations transmitted into buildings or other components
mean a major security risk for people, buildings and machines.
To avoid this we use FEM-programs to plan foundations with
an ideal spring system and seismic mass for your particular
test rig. For this we use the software Nastran for Windows.
The example shown below presents an aluminum vibrating table,
which has been analyzed concerning its natural frequency and
modality with maximum force. The first natural frequency was
required above 100 Hz.
