标准摘要
[中文适用范围]： ISO 18431 的这一部分定义了数学转换（包括物理单位），将每一类振动和冲击数据转换为适合实验之间定量比较和定量规范的形式。 它适用于确定性或随机性、瞬态或连续信号的振动分析。 信号的类别在第 6 条中定义。 要格外小心地正确识别正在分析的信号类型，以便使用正确的变换和单位，特别是在频域分析中。 该数据可以通过实验从机械结构的测量获得或者从机械结构的数值模拟获得。 此类数据非常广泛，因为机械结构种类繁多，例如显微仪器、乐器、汽车、制造机器、建筑物和土木结构。 这些数据可以确定机器或人类对机械振动和冲击的响应。 [外文原描述]： ISO 18431-1:2005 defines the mathematical transformations, including the physical units, that convert each category of vibration and shock data into a form that is suitable for quantitative comparison between experiments and for quantitative specifications. It is applicable to the analysis of vibration that is deterministic or random, and transient or continuous signals. The categories of signals are defined in Clause 6. Extreme care is to be exercised to identify correctly the type of signal being analysed in order to use the correct transformation and units, especially with the frequency domain analysis. The data may be obtained experimentally from measurements of a mechanical structure or obtained from numerical simulation of a mechanical structure. This category of data is very broad because there is a wide variety of mechanical structures, for example, microscopic instruments, musical instruments, automobiles, manufacturing machines, buildings and civil structures. The data can determine the response of machines or of humans to mechanical vibration and shock.
