ISO 18437-1:2012确立了ISO 18437-2至ISO 18437-5的基本原则,用于根据实验室测量确定隔振器中使用的各向同性粘弹性弹性材料的动态机械性能(即弹性模量、剪切模量、体积模量、损耗因子和泊松比)。它还帮助选择本国际标准的适当部分。
ISO 18437-1:2012适用于振动隔离器中使用的各向同性弹性材料,以减少:a)音频振动对结构的传输,例如,可以辐射流体传播的声音(空气传播的、结构传播的或其他);b) 低频振动的传播,例如,当振动太严重时,可能会对人类造成影响或对结构或敏感设备造成损坏;
c) 震动和噪音的传播。
ISO 18437-1:2012中概述的测量方法以及ISO 18437-2至ISO 18437-5中进一步规定的测量方法所获得的数据可用于:1)高效隔振器的设计;2) 为给定设计选择最佳弹性材料;3) 通过隔振器传递振动的理论计算;4) 产品开发过程中的信息;5) 制造商和供应商提供的产品信息;6) 质量控制。
ISO 18437-1:2012 establishes the principles underlying ISO 18437-2 to ISO 18437-5 for the determination of the dynamic mechanical properties (i.e. elastic modulus, shear modulus, bulk modulus, loss factor, and Poisson ratio) of isotropic visco-elastic resilient materials used in vibration isolators from laboratory measurements. It also provides assistance in the selection of the appropriate part of this International Standard.
ISO 18437-1:2012 is applicable to isotropic resilient materials that are used in vibration isolators in order to reduce: a) the transmissions of audio frequency vibrations to a structure that can, for example, radiate fluid-borne sound (airborne, structure-borne or other); b) the transmission of low frequency vibrations which can, for example, act upon humans or cause damage to structures or sensitive equipment when the vibration is too severe; c) the transmission of shock and noise.
The data obtained with the measurement methods that are outlined in ISO 18437-1:2012 and further specified in ISO 18437-2 to ISO 18437-5 can be used for: 1) the design of efficient vibration isolators; 2) the selection of an optimum resilient material for a given design; 3) the theoretical computation of the transfer of vibrations through vibration isolators; 4) information during product development; 5) product information provided by manufacturers and suppliers; 6) quality control.
