The spectrum analysis procedure can be broken down into:

  • Calculating the system’s natural frequencies, mode shapes, and mass participation factors

  • Pulling the corresponding response amplitudes from the spectrum table and calculating the system response for each mode of vibration

  • Combining the modal responses and directional components of the shock.

The first part of the analysis proceeds exactly as in modal analysis.

After natural frequencies are calculated, system displacements, forces, moments, and stresses are calculated and combined on the modal level. After all the results are collected, the Dynamic Output Processor appears. You can review spectral results, natural frequencies, and animated mode shapes.
