Operational vibration analysis
Measurement and evaluation of time-shifted physical parameters such as acceleration, vibration velocities, or vibration displacement paths.

Operational load analysis
Specifying material deformation and transmitted forces and moments in mechanical structures. Determining load ellipses for durability tests.


Eigenfrequency Analysis (FRF)
The natural frequencies of components and component groups are determined by hammer or shaker excitation.

Operational mode shapes
PC-based animation of mode shapes can be carried out by linking geometric data and measurement data.

Experimental modal analysis (EMA)
Identifying the damping matrix and latent vector by introducing an impact (hammer) or through harmonic and noise excitation by means of a shaker.

Operational modal analysis (OMA)
Determination of the damping matrix, as well as eigenmode shapes in operational state without separate excitation.

Human body vibrations
Risk analysis for human exposure to vibration as laid down in the 2002/44/EC directive and ISO 2631 and ISO 5349.

Stroboscopy investigations
Slow-motion representation of vibrations in real objects using video-stroboscopy.

Classification
Specification procedure for damage to mechanical components or component groups by Rainflow and Markov matrices (classification procedure in compliance with DIN 45667).

Fatigue tests
Fatigue tests to establish expected useful life are carried out on a wide variety of test benches (including engine, transmission, roller or turbine test benches and shakers) for vehicles, aircraft or their components. Our service covers the setup, implementation as well as documentation of such test series.
