Examples structural dynamics & vibration analysis
Design for
dynamic stability
Problem
How to ensure that a product will fulfill its dynamics and vibration requirements. From specification to actual design; what is the right approach?
Solution
For optimal solutions, it is important to include dynamic computations in all design phases. To be efficient, different modeling techniques are used for each phase, with different levels of detail and different focus.
Experimental vibrational analysis
Problem
How to verify that a product meets its dynamic requirements. If they are not met, how to find out the cause and how to improve on this?
Solution
By measuring e.g. accelerations, either induced by external forces or under operational conditions, relevant information with respect to the dynamic behavior is gained.
Drop test simulation and experiments
Problem
How to determine if a product will meet its drop and shock testing requirements? Is it possible to predict this during design, so countermeasures are taken if necessary?
Solution
We can perform computer simulations of the drop behavior of a product. We can also perform impact experiments under pre-defined conditions and suggest improvements.
