标准摘要
[中文适用范围]： 本部分 ISO 18431 规定了通过数字滤波器对给定加速度输入的冲击响应谱 (SRS) 进行数字计算的方法。 给出了不同类型冲击响应谱的滤波器系数以及适当采样频率的建议。 [外文原描述]： ISO 18431-4:2006 specifies methods for the digital calculation of a shock-response spectrum (SRS) given an acceleration input, by means of digital filters. The filter coefficients for different types of shock-response spectra are given together with recommendations for adequate sampling frequency.
