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)

Status: Valid

Scope
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 (see Figure 1). NOTE 1 Vibration isolators which are the subject of this part of ISO 10846 are those which are used to reduce the transmission of audiofrequency vibrations (structureborne sound, 20 Hz to 20 kHz) to a structure which may, for example, radiate unwanted fluidborne sound (airborne, waterborne or other). NOTE 2 In practice the size of the available test rig(s) can give restrictions for very small and for very large resilient supports. NOTE 3 Samples of continuous supports of strips and mats are included in the method. Whether or not the sample describes the behaviour of the complex system sufficiently, is the responsibility of the user of this part of ISO 10846. 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 f 2 up to f 3 . The values of f 2 and f 3 are determined by the test set-up and the isolator under test. Typically 20 Hz
