Structural dynamics

We are more and more aware of our environment and what we expose ourselves to. This does not only relate to emissions, but also to disturbing sound and vibrations. It can be of great importance to know how and why your structure shows a dynamic behaviour. It does not necessary need to be destructive for the structure, but it may be experienced as uncomfortable by the end-user. One way to suppress a vibrating behaviour may be through active vibration control.

We can support your company in identifying problem areas by e.g. performing modal analyses to determine frequencies and mode shapes in complex structures. This can be done either by simulations or through measurements. To solve the problem we can apply source- or structural modifications or design passive or active control systems. Our experience in simulating the dynamical behaviour of different types of structures has its origin in the aerospace industry where our associates have been developing systems for Active Vibration Control. The structural dynamic and vibro acoustic simulations are executed in FE-software such as MSC.Nastran and our own tailor-made scripts.

For some applications, high sound pressure levels can cause structural problems in terms of fatigue. This is another area where we combine our knowledge in structural dynamics and acoustics to be able to help our customers to simulate and reduce the fatigue due to high levels of sound pressure. Here too, we can approach the problem either by measurements or simulations.

We have the knowledge to validate and verify our simulations with experimental structural dynamics.
