The RSTD feature occurs in two phases. First, resonant frequencies are detected using a swept sine test measuring the FRF across the control and monitor channels. Multiple FRFs are supported to help detect different sets of resonant frequencies. Afterwards, dwell entries are defined for the relevant resonance frequencies. Tracking (by amplitude or phase) is supported to follow the changes of the resonant frequency as the test progresses. General Features Resonant Frequency Search: Uses Q or amplitude of transmissibility to automatically search the resonances within a certain range. Tracked Dwell: Resonant frequencies are manually entered or loaded from the search table. Dwelling continues until the time duration is reached, resonant frequency changes out of limits, or amplitude changes out of limits. The “tracked dwell” entry must be added to the schedule. Phase Tracked Dwell: Resonant frequencies are manually entered or loaded from the search table. Dwelling continues until time duration is reached or resonant phase changes out of limits. The “Phase Tracked Dwell” entry must be added to the schedule. Users can pre-configure the control level while tracking phase changes. Unique Features in RSTD Vibration Visualization: The EDM Vibration Visualization feature is available in EDM VCS software all test types, including MIMO VCS. This option provides fast and efficient structural model generation and full 3D visualization of the online vibration pattern on the structure under test.
