标准范围
This part of ISO 18431 specifies methods for the digital calculation of a time-frequency analysis of a givensampled measurement of a physical or engineering quantity, such as acceleration, force, or displacement,over an interval of time. Several mathematical formulations of time-frequency transformations aregiven with requirements for recording of parameters and recommendations.The data can be obtained experimentally from measurements of a mechanical structure or obtainedfrom numerical simulation of a mechanical structure. This category of data is very broad becausethere is a wide variety of mechanical structures, e.g. microscopic instruments, musical instruments,automobiles, manufacturing machines, buildings, and civil structures. The data can determine theresponse of machines or of humans to mechanical vibration and shock.
