标准范围

ISO 10846-4:2003规定了两种测定弹性元件（弹性支承除外）平移动态传递刚度的方法。例如弹性波纹管、联轴器、电源电缆、软管和管道吊架。不包括充满液体的元素，如油或水。这些方法适用于带有平法兰或平夹接口的弹性元件。法兰没有必要平行。直接法可用于频率范围从1 Hz到通常由试验装置的框架共振确定的频率（对于尺寸为1 m的试验台，通常为300 Hz）。间接法涵盖的频率范围由试验装置和被测隔离器确定。该范围通常从20 Hz到50 Hz之间的较低频率到2 kHz到5 kHz之间的较高频率。根据ISO 10846-4:2003中规定的方法获得的数据可用于制造商和供应商提供的产品信息、产品开发过程中的信息、质量控制以及通过弹性元件传递振动的计算。

ISO 10846-4:2003 specifies two methods for determining the dynamic transfer stiffness for translations of resilient elements other than resilient supports. Examples are resilient bellows, shaft couplings, power supply cables, hoses and pipe hangers. Elements filled with liquids, such as oil or water, are excluded.The methods are applicable to resilient elements with flat flanges or flat clamp interfaces. It is not necessary that the flanges be parallel.The direct method can be applied in the frequency range from 1 Hz up to a frequency that is usually determined by the frame resonance of the test arrangement (typically 300 Hz for test rigs with dimensions of the order of 1 m).The indirect method covers a frequency range that is determined by the test set-up and the isolator under test. The range is typically from a lower frequency between 20 Hz and 50 Hz to an upper frequency between 2 kHz and 5 kHz.The data obtained according to the methods specified in ISO 10846-4:2003 can be used for product information provided by manufacturers and suppliers, information during product development, quality control, and calculation of the transfer of vibration through resilient elements.
