This module can be used to analyze structures that have been excited with a targeted and known function. The two most common types of excitation are impulse excitation (e.g. with the WaveHitMAX) and shaker excitation. Experimental modal analysis (EMA) determines the modal parameters (eigenfrequencies, mode shapes, and modal damping) of a given structure from measured response functions.
State-of-the-art algorithms are available to extract these modal parameters. Sectional extraction makes this possible even at high modal density.
The module allows the analysis of multiple input and multiple output measurements (SISO, SIMO, MISO, MIMO). Correlation with Finite Element Analysis (FEA) models is possible both visually and computationally (MAC comparison).
Even without expert knowledge, the analysis of vibration measurements succeeds, because suitable algorithms and their parameters can be determined automatically from the input data.
