Acoustics and vibration - Laboratory measurement of vibro-acoustic transfer properties of resilient elements - Part 3: Indirect method for determination of the dynamic stiffness of resilient supports for translatory motion (ISO 10846-3:2002)

This part of ISO 10846 specifies a method for determining the dynamic transfer stiffness for translations of resilient supports, under specific preload. The method concerns the laboratory measurements of vibration transmissibility and is called the indirect method. This method is applicable to test elements with parallel flanges.
Measurements for translations normal and transverse to the flanges are covered in this part of ISO 10846. Annex A provides guidance for the measurement of transfer stiffnesses which include rotatory components.
The method covers the frequency range from f2 up to f3. The values of f2 and f3 are determined by the test set-up and the isolator under test.
The data obtained according to the method specified in this part of ISO 10846 can be used for
product information provided by manufacturers and suppliers,information during product development,quality control, andcalculation of the transfer of vibration through isolators.

Akustik und Schwingungstechnik - Laborverfahren zur Messung der vibro-akustischen Transfereigenschaften elastischer Elemente - Teil 3: Indirektes Verfahren für die Bestimmung der dynamischen Steifigkeit elastischer Elemente für translatorische Schwingungen (ISO 10846-3:2002)

Dieser Teil von ISO 10846 legt für elastische Stützelemente ein Verfahren zur Bestimmung der dynamischen Transfersteifigkeit für Translationsbewegungen unter vorgegebener Vorlast fest. Das Laborverfahren betrifft die Messung der Schwingungsübertragung und heißt Indirektes Verfahren. Das Verfahren ist anwendbar auf Prüfkörper mit parallelen Anschlussflächen (siehe Bild 1).
ANMERKUNG 1   Schwingungsisolatoren, für die dieser Teil von ISO 10846 zutrifft, werden verwendet, um die Übertragung von Schwingungen im Hörfrequenzbereich (Körperschall, 20 Hz bis 20 kHz) auf eine Struktur zu verringern, die z. B. unerwünschten Fluidschall (Luft-, Wasser- oder anderen Schall) abstrahlen kann.
ANMERKUNG 2   In der Praxis kann die Größe der zur Verfügung stehenden Prüfstände die Prüfung sehr kleiner und sehr großer elastischer Stützelemente einschränken.
ANMERKUNG 3   Dieses Verfahren gilt auch für Prüfmuster großflächiger Stützelemente in Streifen und Mattenform. Ob durch das Prüfmuster das Verhalten des gesamten Systems ausreichend beschrieben wird, liegt in der Verantwortung des Anwenders dieses Teils von ISO 10846.

Acoustique et vibrations - Mesurage en laboratoire des propriétés de transfert vibro-acoustique des éléments élastiques - Partie 3: Raideur dynamique en translation des supports élastiques (Méthode indirecte) (ISO 10846-3:2002)

La présente partie de l'ISO 10846 spécifie une méthode pour déterminer la raideur dynamique de transfert en translation de supports élastiques, avec précharge spécifiée. La méthode, dite méthode indirecte, concerne le mesurage en laboratoire de la transmissibilité des vibrations. Elle s'applique aux supports élastiques à brides parallèles.
La présente partie de l'ISO 10846 traite du mesurage des translations normales et transversales aux brides. L'annexe A fournit des lignes directrices pour le mesurage des raideurs de transfert, incluant des composantes rotationnelles.
La méthode couvre la bande de fréquences allant de f2 à f3. Les valeurs de f2 et f3 sont déterminées par le montage d'essai et par l'isolateur soumis à l'essai.
Les données obtenues par la méthode de mesurage spécifiée dans la présente partie de l'ISO 10846 peuvent être utilisées :
comme informations sur les produits à donner les fabricants et les fournisseurs,comme informations au cours de la mise au point du produit,pour le contrôle qualité, etpour le calcul du transfert des vibrations à travers les isolateurs.

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 3.
