| Predmet normy: | This document specifies a method where a vibrating component (a source of structure-borne sound or vibration) is attached to a passive structure (or receiver) and is the cause of vibration in, or structure-borne sound radiation from, the assembly. Examples are pumps installed in ships, servo motors in vehicles or machines and plant in buildings. Almost any vibrating component can be considered as a source in this context. Due to the need to measure vibration at all contact degrees of freedom (DOFs) (connections between the source and receiver), this document can only be applied to assemblies for which such measurement is possible. This document is applicable only to assemblies whose frequency response functions (FRFs) are linear and time invariant. The source can be installed into a real assembly or attached to a specially designed test stand (as described in 5.2). The standard method has been validated for stationary signals such that the results can be presented in the frequency domain. |
