This part of ISO 10846 specifies a method for determining the dynamic transfer stiffness for translations of elastic
supports, under specified preload. The method concerns the laboratory measurement of vibrations on the input side
and blocking output forces and is called the direct method.
The method is applicable to elastic supports 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:
a) the transmission of audiofrequency vibrations (structure-borne sound, 20 Hz to 20 kHz) to a structure which may, for
example, radiate unwanted fluidborne sound (airborne, waterborne or other);
b) 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 vibration is too severe.
NOTE 2 In practice the size of the available test rig(s) may restrict the use of very small or very large elastic supports.
NOTE 3 When an elastic support has no parallel flanges, an auxiliary fixture should be included as part of the test element to
arrange for parallel flanges.
NOTE 4 Portions of continuous supports of strips and mats are used as test samples in this method. Whether or not the
portion describes the behaviour of the complex system sufficiently is the responsibility of the user of this part of ISO 10846.
