What is Shock Response Spectrum (SRS)
A Shock Response Spectrum (SRS) is a graphical presentation of a transient acceleration pulse’s potential to damage a structure. The horizontal axis shows the natural frequency of a hypothetical Single Degree Of Freedom (SDOF), and the vertical axis shows the peak acceleration that this SDOF would undergo as a consequence of the shock input.
A shock response spectrum is a useful tool for estimating the damage potential of a shock pulse, as well as for test level specification.
The shock response spectrum is a calculated function based on the acceleration time history. It applies an acceleration time history as an excitation to an array of single-degree-of-freedom (SDOF) systems. Each system is assumed to have no mass-loading effect on the base input.
