This software specializes in time domain experimental modal analysis for structures, supporting single-input single-output (SISO), single-input multiple-output (SIMO), and multiple-input multiple-output (MIMO) program designs. Unlike traditional modal analysis software based on frequency domain methods requiring Fourier transforms of sampled signals, our implementation processes measured time-domain signals directly. This approach eliminates adverse effects from signal truncation such as spectral leakage, side lobes, and low resolution that impact identification accuracy. The algorithm implementation reduces computational time and enables real-time online parameter identification for structures under actual operating conditions, providing more efficient analysis capabilities compared to conventional Fourier-based methods.
