EN ISO 10846-1:2008

Acoustics and vibration - Laboratory measurement of vibro-acoustic transfer properties of resilient elements - Part 1: Principles and guidelines (ISO 10846-1:2008)

ISO 10846-1:2008 explains the principles underlying ISO 10846-2, ISO 10846-3, ISO 10846-4 and ISO 10846-5 for determining the transfer properties of resilient elements from laboratory measurements, and provides assistance in the selection of the appropriate part of this series. It is applicable to resilient elements that are used to reduce
the transmission of audiofrequency vibrations (structure-borne sound, 20 Hz to 20 kHz) to a structure which may, for example, radiate fluid-borne sound (airborne, waterborne, or other), and
the transmission of low-frequency vibrations (typically 1 Hz to 80 Hz), which may, for example, act upon human subjects or cause damage to structures of any size when the vibration is too severe.

Akustik und Schwingungstechnik - Laborverfahren zur Messung der vibro-akustischen Transfereigenschaften elastischer Elemente - Teil 1: Grundlagen und Übersicht (ISO 10846-1:2008)

Dieser Teil von ISO 10846 erläutert die Grundsätze, die den Labormessungen nach ISO 10846-2, ISO 10846-3, ISO 10846-4 und ISO 10846-5 zur Ermittlung der Transfereigenschaf¬ten elastischer Elemente zugrunde liegen und gibt Hilfe¬stellung bei der Auswahl der jeweils geeigneten Norm dieser Reihe. Er gilt für elastische Elemente, die verwendet werden,
a)   um die Übertragung von Schwingungen im Hörbereich (Körperschall, 20 Hz bis 20 kHz) auf eine Struktur zu verringern; diese Struktur kann z. B. Schall in Fluide abstrahlen (Luftschall, Wasserschall und der¬gleichen);
b)   um die Übertragung tieffrequenter Schwingungen zu verringern (typischerweise 1 Hz bis 80 Hz); solche Schwin¬gungen können z. B. auf den Menschen einwirken oder Schäden an Strukturen beliebiger Größe her¬vor¬rufen, wenn diese Schwingungen zu stark sind.
Die Werte, die nach den Messverfahren ermittelt werden, die in diesem Teil von ISO 10846 umrissen und in ISO 10846-2, ISO 10846-3, ISO 10846-4 und ISO 10846-5 detailliert dargestellt sind, können verwendet werden für
   Produktinformationen, die Hersteller und Lieferanten zur Verfügung stellen,
   Informationen während der Produktentwicklung,
   Qualitätskontrolle,
   die Berechnung der Schwingungsübertragung über ein elastisches Element.
Für die Anwendbarkeit der Messverfahren gelten die folgenden Voraussetzungen:
a)   lineares Schwingungsverhalten des elastischen Elements (dies schließt elastische Elemente mit nicht¬linearer stati¬scher Federkennlinie ein, solange sie näherungsweise lineares Schwingungsverhalten bei einer gegebenen statischen Vorlast zeigen);
b)   die Anschlussflächen, die der Schwingungsisolator mit den angrenzenden Bauteilen der Schwingungs¬quelle und der schwingungsaufnehmenden Struktur gemeinsam hat, können als punktförmig angesehen werden.

Acoustique et vibrations - Mesurage en laboratoire des propriétés de transfert vibro-acoustique des éléments élastiques - Partie 1: Principes et lignes directrices (ISO 10846-1:2008)

L'ISO 10846-1:2008 explique les principes de l'ISO 10846-2, l'ISO 10846-3, l'ISO 10846‑4 et l'ISO 10846-5, destinées à déterminer les propriétés de transfert des éléments élastiques à partir de mesurages en laboratoire, et elle fournit une aide pour choisir la partie appropriée de l'ISO 10846. Elle s'applique aux éléments élastiques destinés à réduire:
la transmission de vibrations de fréquence audible (bruit solidien, 20 Hz à 20 kHz) à une structure qui peut, par exemple, rayonner un bruit propagé par voie fluide (bruit aérien, propagé par l'eau ou autre); et
la transmission de vibrations de basse fréquence (généralement 1 Hz à 80 Hz) qui peuvent, par exemple, agir sur les individus ou endommager les structures de toutes dimensions lorsque la vibration est trop importante.

ISO 10846-1:2008(E)
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. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10846-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise, and
ISO/TC 108, Mechanical vibration, shock and condition monitoring.
This second edition cancels and replaces the first edition (ISO 10846-1:1997), which has been technically
revised.
ISO 10846 consists of the following parts, under the general title Acoustics and vibration — Laboratory
measurement of vibro-acoustic transfer properties of resilient elements:
⎯ Part 1: Principles and guidelines
⎯ Part 2: Direct method for determination of the dynamic stiffness of resilient supports for translatory motion
⎯ Part 3: Indirect method for determination of the dynamic stiffness of resilient supports for translatory
motion
⎯ Part 4: Dynamic stiffness of elements other than resilient supports for translatory motion
⎯ Part 5: Driving point method for determination of the low-frequency transfer stiffness of resilient supports
for translatory motion

Introduction
Passive vibration isolators of various kinds are used to reduce the transmission of vibrations. Examples
include automobile engine mounts, resilient supports for buildings, resilient mounts and flexible shaft
couplings for shipboard machinery and small isolators in household appliances.
This part of ISO 10846 serves as an introduction and a guide to ISO 10846-2, ISO 10846-3, ISO 10846-4 and
ISO 10846-5, which describe laboratory measurement methods for the determination of the most important
quantities which govern the transmission of vibrations through linear resilient elements, i.e.
frequency-dependent dynamic transfer stiffnesses. This part of ISO 10846 provides the theoretical background,
the principles of the methods, the limitations of the methods, and guidance for the selection of the most
appropriate standard of the series.
The laboratory conditions described in all parts of ISO 10846 include the application of static preload, where
appropriate.
The results of the methods are useful for resilient elements, which are used to prevent low-frequency vibration
problems and to attenuate structure-borne sound. However, for complete characterization of resilient elements
that are used to attenuate low-frequency vibration or shock excursions, additional information is needed,
which is not provided by these methods.
