AEDC has developed a model-based analysis tool that merges real time processed dynamic engine vibration data with finite element models (FEM) and pretest analysis results. The tool, called the Structural Dynamics Response Analysis Capability, or SDRAC, performs this merge, displays the analysis results via an interactive graphical user interface (GUI) and presents an assessment of structural capability in real time. The tool also features a model modification routine to insure that the mathematical simulation adequately reflects results from the test. The adequacy of the simulation is displayed via error measures.
