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, waterbome 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 f2 up to f3. The values of f2 and f3 are determined by the test set-up and the isolator under test. Typically 20 Hz ≤f2 ≤ 50 Hz and 2 kHz ≤f3 ≤ 5 kHz. 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. NOTE 1 When a resilient support has no parallel flanges, an auxiliary fixture should be included as part of the test element to arrange for parallel flanges. NOTE 2 Arrows indicate load direction.
