HP-MTAS is a professional modal testing and analysis software suite designed for structural dynamics and vibration engineering. It helps engineers turn raw test data into reliable modal parameters (frequency, damping, mode shapes) with high-precision algorithms, interactive 3D geometry modeling, real-time test monitoring, and rich visualization (FRF plots, waterfall, ODS animations).
| Faster modal results | Go from raw time data → FRF (H1/H2/H3/H4) → modal parameters (frequency/damping/mode shapes) in one workflow. |
|---|---|
| Higher identification accuracy | Use LSCE / STLSCE and stabilization diagrams to cross-check poles and improve damping ratio estimation. |
| Less rework during testing | Monitor signals and test progress in real time, then adjust sampling, averaging, and setup before re-running tests. |
| Clearer engineering communication | Visualize results with FRF curves, spectra, waterfall plots, and 3D mode/ODS animations so non-experts can understand quickly. |
| More flexible data handling | Import/export UFF, TXT, and Excel to connect with DAQ systems and downstream analysis/reporting needs. |
| Cleaner, repeatable comparisons | Control window functions (Rectangular, Hanning, Hamming, Blackman, Welch, Kaiser), averaging methods, and frequency settings for consistent results. |
| Faster delivery to customers | Auto-generate DOC reports with customizable templates to reduce manual formatting time. |
