Shock Response Spectrum (SRS)

Shock response spectrum (SRS) analysis

The Shock Response Spectrum (SRS) is used to determine the damage potential of components and systems from transient events, such as pyroshocks, in order to ensure their survival in known environments.

Ask an Expert

A single transient shock event such as a pyroshock or a structural impact can damage components in a structural system. Similarly, earthquakes can cause catastrophic failures in bridges and buildings. And with any motion input into a system, the response can be amplified by structural resonances, increasing the damage. 

By calculating the shock response spectrum (SRS) from transients in the time domain, it can be determined how shocks affect a structure.

BK Connect Shock Response Spectrum Analysis software supports all five SRS models described in the ISO 18431-4:2007 standard. Combined with the nine ordinary criteria for amplitude calculations (shock instances), up to 45 response types can be calculated to match your requirements.

Special shock accelerometers for high-level and high-frequency measurements are part of our complete measurement and analysis chain.
