Detailed Documentation
One of the frequency-domain modal parameter identification methods can analyze and process vibration signals to determine structural natural frequencies, damping ratios, and mode shape coefficients. This method proves highly effective with comprehensive program implementation featuring signal preprocessing, frequency response function estimation, and peak-picking algorithms. Furthermore, these identified parameters enable advanced studies of structural dynamic characteristics, such as resonance phenomena and variations in vibration modes. Through this approach, we gain deeper insights into structural vibration behavior, providing enhanced guidance and support for engineering applications. The implementation typically involves MATLAB or Python scripts utilizing FFT transformations, complex modal analysis, and orthogonal polynomial fitting techniques for accurate parameter extraction.
