Vibration Reduction with Passive and Active Dampers

Vibrations play a crucial role regarding fatigue and acoustics of wind turbines. They cannot be avoided completely, therefore they have to be controlled and reduced as much as possible.

Unwanted vibrations occur in almost all industries and applications. As experts for vibrations and acoustics, we have vast experience in the field of vibration reduction and with our extensive knowledge of structural mechanics and dynamics, we have specialized in solving vibration problems.

In addition to conventional measures, such as detuning, we provide a wide range of passive and active absorber concepts, which we successfully apply to  various industries. Tuned mass dampers are mounted directly on the vibrating structure – if possible, very close to the affected area – and have a vibration-reducing effect.

If we are already involved in the product development process, we work out solutions mainly by means of FE simulation and measurements. If damping devices are considered as an option for vibration optimization in the design process, they can be conveniently integrated in the structural design. Also for existing structures with an excessively high level of vibration, damping devices are an effective option to solving the problem.

Within the wind energy sector, we offer customized solutions in the field of low-frequency structural vibrations and tonalities. The reduction of structural vibrations is usually intended to reduce mechanical stress, the reduction of structure-borne sound is intended to reduce tonal sound radiations.
