Calculation of a shock response spectrum

Abstract

As it is stated in the ISO 18431–4 Standard, a Shock Response Spectrum is defined as the response to a given acceleration acting at a set of mass-damper-spring oscillators, which are adjusted to the different resonance frequencies while their resonance gains (Q-factor) are equal to the same value. The maximum of the absolute value of the calculated responses as a function of the resonance frequencies compose the shock response spectrum (SRS). The paper will deal with employing Signal Analyzer, the software for signal processing, for calculation of the SRS. The theory is illustrated by examples.
