This section provides a direct measurement of linear elastic supporting elements dynamic stiffness function. As long as their performance in a given static preload Approximate linear vibration characteristics, the nonlinear static pre-load - displacement characteristics of the resilient support member may also be measured using this method. Headquarters The elastic element into vibration - acoustic transfer properties of one of the series standard laboratory measurement methods, the series also includes a standard measurement principle, indirectly measured The amount and method of driving point of law related content. Part 1 provides a standard selection criteria applicable to this series of guide portion. Laboratory conditions described in this section involves the use of static preload. This section describes the results obtained by the method adapted to prevent low-frequency vibration and reduce sound structure of the elastic support member. However, this method It can not provide a complete description of further information on the elastic member for attenuating low frequency vibration and shock offsets, the need for additional information to elaborate. Sound and vibration elastic element vibration - acoustic transfer Characteristics laboratory measuring methods - Part 2. Flexible Direct measurement method supports translational dynamic stiffness1 ScopeThis section GB/T 22159 requirements for a given pre-load elastic supports translational movement measuring method stiffness. The method involves input End blocking output force and vibration laboratory measurements, referred to as "direct measurement approach." This method is applicable to a portion of the test element parallel flanges (see Fig. 1). a) b) c) Note 1. If the elastic supporting member does not have a parallel flanges, requires the use of a parallel flange having an auxiliary fixture and test it as a member Points, in order to meet the conditions required for the measurement. Note 2. the load is shown by the arrow direction of FIG.1 with parallel flange elastic supporting member exampleThe elastic element in this section are directed mainly used to reduce. a) the audible sound of low frequency (typical value is between 20Hz ~ 500Hz) of the structure-borne vibration, which can sometimes lead to structural radiation Undesired fluid sound (sound such as air, water, sound, or other media voices). b) low frequency vibration (typical value is between 1Hz ~ 80Hz) can be spread in the human body, or when such vibration is very grave, Any size member hazard. Note 1. In fact, due to the size limit testing device, the method can not be used too big or too small elastic supporting member. Note 2. This method can also be used for continuous sample support member with reed mats and strips constructed. These samples can be fully described in this Part is characteristic of complex systems Sub-user responsibility. This section covers the test element and the vertical flange and parallel translational measurements. Direct measurement of the frequency range applicable law is 1Hz ~ fUL, fUL usually depends on test systems. Note 3. Due to the type of test systems and test element of variety, so fUL usually change. In this section, there is no test system defines a fixed Frequency range, but the actual test data subject, such as the 6.1 to 6.4. This section uses the measurement data obtained by the method can be used. --- Production and supply product information provided by manufacturers; --- The product development process the required information; --- Product quality control; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22159.2-2012_English be delivered?Answer: Upon your order, we will start to translate GB/T 22159.2-2012_English as soon as possible, and keep you informed of the progress.
