ISO 10846-3:2002

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

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, and
• calculation of the transfer of vibration through isolators.
