GB/T 22159.3-2008/ISO 10846-3.2002IntroductionVarious passive isolators are used to reduce the transmission of vibration, such as automobile engine mounts, resilient support buildings, marine shells machine Of support and flexibility (flexible) coupling and small household appliances in the isolator. This section provides linear elastic support dynamic stiffness measurement function indirect method, if the elements of a given static preload exhibit similar Linear vibration characteristics, this section also includes the non-linear static pre-load - deflection characteristics of elastic support. This section elastic element vibration - acoustic characteristics of the standard series of laboratory measurements, the series also includes a standard measurement principle, directly Driving method and point method, ISO 10846-1 provides a general guide to select the appropriate standard. Laboratory conditions as described in this section contains information on how the rational use of static preload. Indirect method for the analysis of the elastic element 20Hz or more Structure-borne sound transmission loss is very useful. However, this method can not be fully characterized for attenuating low frequency vibration or shock isolator displacement characteristics. GB/T 22159.3-2008/ISO 10846-3.2002 Sound and vibration elastic element vibration - acoustic transfer Characteristics laboratory measuring methods - Part 3. Flexible Support translational motion indirect measurement of stiffness1 ScopeThis section details given in a preloaded condition, resilient supports translational motion measurements stiffness. The method mainly involves Laboratory measurement of vibration transmissibility, called indirect method of measurement. This method is suitable for testing components in parallel with the connecting member (see Figure 1). Note 1. This section applies to those to reduce vibration audio (20Hz ~ 20kHz sound structure) to the structure of the main transmission of vibration isolators. This type Vibration can radiate unwanted fluid sound (sound such as air, water, sound, or other). Note 2. In the actual case, the test device size limitations, the method is not used for very small or very large elastic support. Note 3. This method is also included in the support portion of the continuous measurement sample pad. These samples can be fully showed the characteristics of complex systems used by this section Responsible. This section also describes the parallel displacement measuring method and in the vertical direction with the DUT connection. Appendix A contains genetically introduced Guiding measurement dynamic stiffness of the movable member. This section uses the measurement data obtained by a method that can be used. --- Production and supply product information provided by manufacturers; --- Information on the product development process required; ---QC; --- Calculated by the vibration isolator transmissibility. Note 1. when the elastic member is not parallel with the connecting member, and the need to use auxiliary fixing jig member as part of the test, to meet the required measurements Parallel connections conditions. Note 2. the load is shown by the arrow direction of FIG. Figure 1 has a parallel connection of the elastic support member2 Normative referencesThe following documents contain provisions which, through reference GB/T 22159 in this section constitute provisions of this section.
