Acoustics and vibration - Laboratory measurement of vibro-acoustic transfer properties of resilient elements - Part 5: Driving point method for determination of the low-frequency transfer stiffness of resilient supports for translatory motion (ISO 10846-5:2008)

ISO 10846-5:2008 specifies a driving point method for determining the low-frequency transfer stiffness for translations of resilient supports, under a specified preload. The method concerns the laboratory measurement of vibrations and forces on the input side with the output side blocked, and is called the “driving point method”.
The stiffness resulting from measuring the input displacement (velocity, acceleration) and input force is the dynamic driving point stiffness. Only at low frequencies, where the driving point stiffness and the transfer stiffness are equal, can this method be used for determination of the dynamic transfer stiffness.
The method is applicable to test elements with parallel flanges.

Akustik und Schwingungstechnik - Laborverfahren zur Messung der vibro-akustischen Transfereigenschaften elastischer Elemente - Teil 5: Ermittlung der Transfersteifigkeit elastischer Stützelemente aus der Eingangssteifigkeit bei Anregung in translatorischer Richtung und tiefen Frequenzen (ISO 10846-5:2008)

Dieser Teil von ISO 10846 legt ein Verfahren zur Ermittlung der Transfersteifigkeit elastischer Stützelemente aus der Eingangssteifigkeit in translatorischer Richtung bei tiefen Frequenzen unter einer vorgegebenen Vorlast fest. Das Laborverfahren umfasst die Messung der Schwingungen und Kräfte auf der Eingangsseite bei fester Einspannung auf der Ausgangsseite und heißt "Verfahren unter Verwendung der Eingangssteifig-keit".
Die anhand von Messungen des Schwingwegs (der Schwinggeschwindigkeit/Schnelle, der Beschleunigung) und der Kraft auf der Eingangsseite erhaltene Steifigkeit ist die dynamische Eingangssteifigkeit. Lediglich bei tiefen Frequenzen, bei denen die Eingangssteifigkeit und die Transfersteifigkeit gleich sind, kann dieses Verfahren zur Ermittlung der dynamischen Transfersteifigkeit herangezogen werden.
ANMERKUNG 1   In ISO 10846-2 wird das direkte Verfahren zur Messung der dynamischen Transfersteifigkeit behandelt. Beim direkten Verfahren wird die tieffrequente dynamische Transfersteifigkeit ermittelt, und das Verfahren umfasst prinzipiell einen breiteren Frequenzbereich als das Verfahren unter Verwendung der Eingangssteifigkeit. Das Verfahren unter Verwendung der Eingangssteifigkeit wird jedoch in der internationalen Normenreihe ISO 10846 ebenfalls beschrieben. Es bietet Besitzern von (häufig teuren) Prüfaufbauten zur Messung der dynamischen Eingangssteifigkeit eine nützliche Möglichkeit, diese Prüfaufbauten ebenso zur Ermittlung der tieffrequenten dynamischen Transfersteifigkeit  zu verwenden.
Das Verfahren gilt für Prüfkörper mit parallelen Anschlussflächen (siehe Bild 1).
Elastische Elemente, für die dieser Teil von ISO 10846 zutrifft, werden verwendet,
a)   um die Übertragung von Schwingungen im tieffrequenten Teil des Hörbereichs (typischerweise 20 Hz bis 200 Hz) auf eine Struktur zu verringern; diese Struktur kann z. B. unerwünschten Schall in Fluide abstrah-len (Luftschall, Wasserschall und dergleichen);

Acoustique et vibrations - Mesurage en laboratoire des propriétés de transfert vibro-acoustique des éléments élastiques - Partie 5: Méthode du point d'application pour la détermination de la raideur dynamique de transfert basse fréquence en translation des supports élastiques (ISO 10846-5:2008)

L'ISO 10846-5:2008 spécifie une méthode du point d'application pour déterminer la raideur de transfert à basse fréquence en translation de supports élastiques, avec précharge spécifiée. La méthode, qui concerne le mesurage en laboratoire des vibrations et forces à l'entrée, avec blocage en sortie de l'isolateur de vibrations, est désignée sous le nom de «méthode du point d'application».
La raideur déterminée par mesurage du déplacement à l'entrée (vitesse, accélération) et de la force à l'entrée est la raideur dynamique au point d'application. Cette méthode ne peut être utilisée pour la détermination de la raideur dynamique de transfert qu'à basse fréquence, lorsque la raideur au point d'application et la raideur de transfert sont égales.
La méthode s'applique lors des essais d'éléments élastiques à brides parallèles.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights.
