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.
Abstract
Overview
ISO 18431-4:2007 - "Mechanical vibration and shock - Signal processing - Part 4: Shock-response spectrum analysis" defines standardized digital methods to calculate a from an acceleration time record. The standard specifies how to model a set of single-degree-of-freedom (SDOF) oscillators, the transfer functions used to obtain maximum responses versus natural frequency, and the digital-filter approach (including the Ramp Invariant Method) to produce accurate SRS results. It also provides filter coefficient formats and .
