Generate a shock response spectrum (SRS) from a time waveform to analyze environments with complex transient events. Use the software tools to create an SRS test equivalent to the operational environment or validate an SRS test profile before running it on a shaker.
All Software FeaturesEngineers use the shock response spectrum (SRS) to develop a test profile that simulates complex transient events. ObserVIEW’s innovative analysis tool allows them to evalute a recorded shock waveform or an SRS test profile.
Use the analysis ranges tool to define separate shock events in a single time waveform and generate an SRS for each event. Alternatively, add multiple time waveform files to a project to analyze individually recorded events side-by-side.
With SRS in ObserVIEW, you can generate an SRS test profile from recorded data that can run on a shaker in the lab. The process takes seconds: simply copy the SRS trace and paste it to the test profile SRS breakpoint in the VibrationVIEW software.
For a more comprehensive test profile, envelope the SRS traces from multiple recorded waveforms using the software’s Math Traces feature.
The SRS is a model of a test article’s maximum response to a transient event. Engineers use a synthesized SRS pulse to evaluate the test article’s behavior during and after a complex shock event, such as earthquakes, rocket separation, and shipboard shock.
For analysis, engineers can use the SRS to compare the damage potential of shock events for qualification or validation.
Validate an SRS test profile before you run it on a shaker. You can use the tolerance lines to confirm that each pulse reaches the SRS demand and is in tolerance.
Perform the validation live by connecting to Live Analyzer. A live SRS with pasted traces will display the tolerance and demand lines from the test, allowing you to watch and validate the SRS test in the software.
This VR tech talk discusses the process of developing SRS test specifications, including common problems and suggested practices.
