Fraunhofer LBF entwickelt Prüfstand zur Messung von Torsionsschwingungen

(PresseBox) (Darmstadt, )
Torsionsschwingungen an drehenden Wellen sind vor allem in mechanischen Antriebssystemen unerwünscht. Automobil- und Maschinenbauer begegnen ihnen mit aktiven und passiven Schwingungsdämpfern und Schwingungstilgern. Eine Voraussetzung für deren Einsatz ist die genaue Kenntnis des dynamischen Verhaltens des Dämpfers oder Tilgers. Das Fraunhofer-Institut für Betriebsfestigkeit und Systemzuverlässigkeit LBF hat für diesen Zweck einen Prüfstand zur dynamischen Charakterisierung derartiger Rotationssysteme entwickelt.

Rotierende Komponenten führen zu Eigenfrequenzen des Gesamtsystems. Mit zunehmender Optimierung auf Gewicht und Wirkungsgrad werden vor allem Antriebsstränge immer leichter zu unerwünschten Torsionsschwingungen angeregt. Werden diese durch Resonanz verstärkt, wird es gefährlich: Bauteile können versagen. Schall und Vibrationen stören den Komfort. Dämpfungssysteme ysx Sqlceh llummd Wunoffd lqffaayh.
