The Shock Response Spectrum (SRS) software option adds SRS plots to VibrationVIEW’s Shock and Transient Capture test modes. Define the SRS parameters and synthesize a pulse to meet a specified curve. The software includes a variety of waveform synthesis generation techniques.

Define the SRS test settings and synthesize the pulse to meet a specified curve. VibrationVIEW supports over 200 individual breakpoints, suitable for virtually any test specification.
Test generation techniques include:
Alternatively, iterate an SRS curve from a field-recorded time waveform.
Synthesize a pulse to match a specified SRS curve. You can manually adjust the parameters of the underlying wavelets or allow VibrationVIEW to automatically create and run a test without intervention.
In VibrationVIEW, you can modify a field-recorded time waveform to meet or exceed a specified SRS curve. The resulting time waveform reflects the end-use environment and has the same frequency response function.
A waveform based on an enveloped set of field recordings maintains real-world characteristics and creates an SRS waveform that accurately reflects the real-world application. Read more: Using Recorded Data to Improve SRS Test Development.
The SRS is a method of testing components against complex transient shock events using a synthesized pulse. While designed to evaluate structural responses to earthquakes, engineers now use SRS tests to measure a component’s response to transient events likely to occur in the end-use environment in fields such as aerospace, defense, and seismic.
An SRS test generates more complex shock pulses than a classical shock test. Engineers often synthesize one of several standard synthetic waveforms, such as burst random or WavSyn, to develop a custom SRS response. Read more: Characteristics of SRS Waveforms.
The SRS is a representation of time-domain data in the frequency domain. It models the original waveform’s response channels using a set of theoretical, single-degree-of-freedom (SDOF), mass-damper-spring oscillators. The SRS sequentially applies filters of increasing frequency to the time domain data and plots the characteristics of the filtered waveform.
The horizontal axis of the plot represents the natural frequency of each SDOF. The theoretical response of each SDOF is plotted on the vertical axis. It is important to note that the SRS is not the actual response of the device under test but a theoretical representation of the response.
