Description / Abstract:
This part of ISO 18437 establishes the principles underlying ISO
18437-2 to ISO 18437-5 for the determination of the dynamic
mechanical properties (i.e. elastic modulus, shear modulus, bulk
modulus, loss factor, and Poisson ratio) of isotropic visco-elastic
resilient materials used in vibration isolators from laboratory
measurements. It also provides assistance in the selection of the
appropriate part of this International Standard.
This part of ISO 18437 is applicable to isotropic resilient
materials that are used in vibration isolators in order to
reduce:
a) the transmissions of audio frequency vibrations to a
structure that can, for example, radiate fluid-borne sound
(airborne, structure-borne or other);
b) the transmission of low frequency vibrations which can, for
example, act upon humans or cause damage to structures or sensitive
equipment when the vibration is too severe;
c) the transmission of shock and noise.
The data obtained with the measurement methods that are outlined
in this part of ISO 18437 and further specified in ISO 18437-2 to
ISO 18437-5 can be used for:
1) the design of efficient vibration isolators;
2) the selection of an optimum resilient material for a given
design;
3) the theoretical computation of the transfer of vibrations
through vibration isolators;
4) information during product development;
5) product information provided by manufacturers and
suppliers;
6) quality control.
