适用范围：This part of ISO 10846 explains the principles underlying ISO 10846-2, ISO 10846-3, ISO 10846-4 andISO 10846-5 for determining the transfer properties of resilient elements from laboratory measurements, andprovides assistance in the selection of the appropriate part of this series. It is applicable to resilient elementsthat are used to reducea) the transmission of audio frequency vibrations (structure-borne sound, 20 Hz to 20 kHz) to a structurewhich may, for example, radiate fluid-borne sound (airborne, waterborne, or other), andb) the transmission of low-frequency vibrations (typically 1 Hz to 80 Hz), which may, for example, act uponhuman subjects or cause damage to structures of any size when the vibration is too severe.The data obtained with the measurement methods, which are outlined in this part of ISO 10846 and furtherdetailed in ISO 10846-2, ISO 10846-3, ISO 10846-4 and ISO 10846-5, can be used for⎯ product information provided by manufacturers and suppliers,⎯ information during product development,⎯ quality control, and⎯ calculation of the transfer of vibrations through resilient elements.The conditions for the validity of the measurement methods area) linearity of the vibrational behaviour of the resilient elements (this includes elastic elements withnon-linear static load-deflection characteristics, as long as the elements show approximate linearity forvibrational behaviour for a given static preload), andb) the contact interfaces of the vibration isolator with the adjacent source and receiver structures can beconsidered as point contacts.
