  text: Die Bestimmung des Frequenzübertragungsverhaltens von Strukturen mit nichtlinearer
    Charakteristik ist eine im technischen Bereich vielfach auftretende Aufgabe, z.B.
    für die genaue Bestimmung dynamischer Eigenschaften in der Entwurfsphase oder
    bei der Parametrierung von Modellen. Die typisch angewandten Verfahren zur Schwingungsmessung
    solcher Strukturen legen in der Regel ein lineares Strukturverhalten zu Grunde,
    oder sie erfordern einen hohen Zeit- und Messaufwand für die Abbildung des nichtlinearen
    Verhaltens; häufig in Verbindung mit einer starken Belastung der zu testenden
    Struktur. Die Bestimmung nichtlinearen Strukturverhaltens ist somit oft nicht
    effizient realisierbar. In der vorliegenden Arbeit wird ein neuer Ansatz zur Schwingungsanalyse
    nichtlinearer Strukturen mit von der Anregungsamplitude abhängigem Übertragungsverhalten
    vorgestellt. Dabei liegt ein Schwerpunkt auf der messtechnischen Bestimmung des
    nichtlinearen Verhaltens bei deutlich reduziertem Zeit- bzw. Messaufwand. Das
    Verfahren basiert auf einer Messmethode, die eine effiziente Bestimmung des nichtlinearen
    Kennfeldes der analysierten Struktur mit speziellen multiharmonischen Anregungssignalen
    ermöglicht. In Kombination mit einem fortschrittlichen Auswertealgorithmus kann
    eine vollständige Beschreibung des dynamischen Verhaltens in Form eines charakteristischen
    Diagramms generiert werden. Das Messverfahren wird durch eine Identifikationsroutine
    ergänzt, die die erforderliche Anzahl an Messungen nochmals reduzieren kann. Es
    ist als Mess-System auf Hard- und Software implementiert; der Funktionsnachweis
    erfolgt an verschiedenen Beispielen.

  text: A measurement method is presented that combines the advantages of the multisine
    measurement technique with a prediction method for peak bending behavior. This
    combination allows the analysis of the dynamic behavior of mechanical structures
    at distinctly reduced measurement durations and has the advantage of reducing
    high excitation impacts on the structure under test.

  text: Many nonlinear mechanical oscillators show excitation-dependent behavior.
    In this paper, a new measurement approach is presented to analyze such structures.
    The main advantage of the presented method is the high efficiency, since measurement
    duration and loads to the structure are significantly reduced.
