ISO 10846-2:2008规定了在规定的预载下，测定弹性支架平移的动态转移刚度的方法。该方法涉及实验室对输入侧振动和阻塞输出力的测量，称为“直接法”该方法适用于带有平行法兰的测试元件（见图1）。ISO 10846-2:2008规定的弹性元件是用于减少可听见频率范围（通常为20 Hz至500 Hz）较低部分的振动传递到结构，例如，该结构可能会辐射不必要的流体传播声音（空气传播、水传播或其他），以及低频振动的传播（通常为1 Hz至80 Hz），例如，当振动太严重时，可能会作用于人体或对任何尺寸的结构造成损坏。

ISO 10846-2:2008 specifies a method for determining the dynamic transfer stiffness for translations of resilient 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 test elements with parallel flanges (see Figure 1).Resilient elements, which are the subject of ISO 10846-2:2008, are those which are used to reducethe transmission of vibration in the lower part of the audible frequency range (typically 20 Hz to 500 Hz) to a structure which may, for example, radiate unwanted fluid-borne sound (airborne, waterborne or others), andthe 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.
