Dämpfung in verspannten Fugen

Abstract: Kurzfassung Im Rahmen der Analyse und Bewertung des dynamischen Verformungsverhaltens und der Prozessstabilität von Werkzeugmaschinen kommt der modellgestützten Ermittlung von Nachgiebigkeitsfrequenzgängen eine zentrale Bedeutung zu. Die Aussagekraft dieser Frequenzgänge wird dabei wesentlich von der treffenden Berücksichtigung der Dämpfung – in Ansatz und Parametrik – bestimmt. Einen wesentlichen Anteil an der Systemdämpfung leistet dabei die lokale Fugendämpfung in Pressverbindungen, deren Wir… Show more

“…Substituting the system and element stiffness matrix of demonstrated joint with FeGr disc in equations (22) and (23), the damping ratio dl of the whole system for a certain mode l results inwhere the loss factor of the material is from Kollmann (2006), and according to Rudolph and Ihlenfeldt (2017), the loss factor of a tightly fastened screw connection from the surface pressure of 24 MPa can be treated constant and approximates 0.03.…”
