EarthquakeTesting

A variety of waveform synthesis generation techniques included.

    Easy test entry
    Frequency/amplitude breakpoints of the background random acceleration spectrum are entered in an easy to read tabular form using frequency and amplitude breakpoints. 200 separate frequency/amplitude breakpoints can be entered, allowing entry of virtually any test.

    SRS analysis test
    SRS Package adds SRS plots to shock and transient capture test modes

    Multi-Axis Control
    Test for Multi-Axis Control

    Specifications Supported include

    • IEEE 344 Recommended Practice for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Stations
    • IEEE 382 Standard for Qualification of Actuators for Power-Operated Value Assemblies With Safety-Related Functions for Nuclear Power Plants

    IEEE344 Features

    • Input filtering for measurement of zero period acceleration (IEEE344-Annex A) Multiple damping plots (IEEE344-Annex A)
    • Time interval waterfall PSDs (IEEE344 - Annex B)
    • Sine Beat/Dwell/Sweep Fragility Testing (IEEE344 - Annex C)
    • Peak stress cycle counting (IEEE344 - Annex D)
    • Coherence Plots (IEEE344 - Annex E)

    SRS generation
    Supports many waveform generation techniques including linear and exponential chirp, wavesyn, burst random, linear and exponential chirp on burst random, enveloped random, burst sine, or iterate from user waveform.

    Manual Wavelet manipulation
    Manually adjust all the parameters of the underlying wavelets, or allow VibrationVIEW to automatically create and run without intervention

    Data plots
    SRS Pseudo Velocity and SRS Acceleration plots. Acceleration for primary (+), primary (-), or Maxi-Maxi. Graphs can be easily auto-scaled or zoomed, and cursors displayed. Data and text annotations can be easily placed on the graphs, with data values updated live as the data changes
