Vibrations Department
Research at the ISD is mainly motivated by questions from wind energy technology and aerospace, but current challenges from lightweight automotive construction and building construction are also addressed. Modeling, simulation and experiment are the focus of all research fields.
Methods for early damage detection are developed for slender, vibration-prone structures (e.g. support structures and rotor blades of wind turbines). Fast simulation and optimisation procedures are provided for coupled systems (e.g. onshore and offshore wind turbines). The focus is also on models of sound propagation (air and water sound).
Scale based models of material and progressive failure behavior under static and cyclic loads are developed for fiber composite lightweight construction. New structural concepts, e.g. processed using variable fiber orientations and morphing systems.
In many cases, fuzzy information plays an important role. Application-based methods are therefore further developed for the research fields of the ISD.
Based on many years of research expertise, the ISD works for industry and authorities, carries out vibration and noise measurements as well as provides reports and recommendations for vibration and noise reduction.
The trend towards slender structures and the development of high performance lightweight materials increased structural vibrations under dynamic excitation due to wind, waves, people or earthquake. Research is orientated towards development of models representing reality and reduction of vibrations and noise. Validation of numerical models, which is of special importance in dynamics, is performed by measuring on mostly full scale structures.
Composite materials combine the advantages of its constituents and because of their excellent properties have a continuously increasing importance. The department “Composites” is working in research and industrial projects on the numerical analysis of composite materials and composite structures.
