A tool for analysing shocks

Abstract

The paper deals with evaluation the shock response spectrum (SRS), which is employed to analysis of impulse signals. This kind of spectra is a set of the minimum or maximum values of the time response produced by the single degree-of-freedom (SDOF) system, which is tuned to a set of resonance frequencies, to a shock signal. The response is evaluated as an output of the second order infinite response filter (IIR) with an input, which is the sequence of the acceleration signal samples. The theory is illustrated by examples.
