Shock Response Spectrum (SRS) |

Accessible through menu option *Signal tools/Shock Response Spectrum (SRS)*

Shock Response Spectrum (SRS) is a graphical representation of an arbitrary transient
acceleration input, such as shock in terms of how a Single Degree Of Freedom (SDOF) system
(like a mass on a spring) responds to that input.

Actually, it shows the peak acceleration response of an infinite number of SDOFs, each of which
have different natural frequencies. Peak acceleration response is represented on the Y-axis, and
natural frequency of any given SDOF oscillator is shown on the X-axis.

SRS plot in *SIGVIEW *can automatically use Octave-based** frequency spacing**: you can choose
between 1/24, 1/12, 1/6, 1/3 and linear frequency scaling. Also, you can speed-up calculation by
limiting the frequency range (**min/max frequency values**).

The level of damping is demonstrated by the **"quality factor", Q **which can also be thought of
transmissibility in sinusoidal vibration case. Relative damping of 5% results in a Q of 10.

After choosing SRS option from the main menu, the following dialog will appear where you can
set all calculation parameters:

As a result, SRS plot will appear in a new window.
