QL-MODALSENSE-AI – AI-Assisted Modal Analysis Software

QuakeLogic QL-MODALSENSE-AI is AI-assisted modal analysis software for structural health monitoring and vibration testing. It provides real-time monitoring of 24 acceleration channels, automated modal identification, and interactive 3D mode shapes. Moreover, the software calculates natural frequencies, damping ratios, and MAC values. Its browser-based interface also enables convenient on-site analysis through the QuakeVault edge server.

OVERVIEW

Description

QuakeLogic QL-MODALSENSE-AI is advanced AI-assisted modal analysis software for structural health monitoring, vibration analysis, and modal testing. It combines real-time sensor monitoring, signal processing, and structural mode identification in one platform.

Moreover, the software helps engineers analyze natural frequencies, damping ratios, and structural mode shapes. Its browser-based interface also simplifies data access during field testing.

Advanced Structural Health Monitoring

QL-MODALSENSE-AI works with QL-MODALINK triaxial sensor nodes and the QuakeVault edge server. The standard system supports eight sensor nodes and 24 acceleration channels.

In addition, the software synchronizes all measurements using one common time base. Therefore, engineers can analyze structural responses without manually aligning separate recordings.

Users can monitor acceleration, RMS, peak values, noise levels, and tilt in real time. Furthermore, the software displays sensor status and data availability during each measurement session.

AI-Assisted Modal Identification

QL-MODALSENSE-AI simplifies modal analysis through intelligent signal processing and AI-assisted peak picking.

First, the software processes vibration records using filtering, detrending, and spectral analysis. Next, it calculates the singular value spectrum to identify potential structural modes.

Then, AI-assisted peak detection identifies modal frequencies and provides confidence values. Engineers can also review and adjust the results manually.

Additionally, the software calculates damping ratios and Modal Assurance Criterion (MAC) values. As a result, users gain valuable information about structural dynamic behavior.

Interactive Mode Shape Visualization

The software displays structural mode shapes directly on the structure geometry. Users can explore vibration patterns through 3D, plan, and elevation views.

Moreover, the integrated MAC matrix helps engineers compare identified modes. The software also supports amplitude scaling for bending, torsional, and lateral vibration modes.

Consequently, engineers can evaluate structural behavior through clear visual results.

Real-Time Monitoring and Data Management

QL-MODALSENSE-AI provides a live multi-channel dashboard for structural monitoring projects.

For example, engineers can view acceleration signals from multiple sensor locations in one window. They can also monitor network health, temperature, noise levels, and data completeness.

Furthermore, QuakeVault stores measurement records locally. Therefore, users do not need cloud storage for normal system operation.

The software also supports ASCII, CSV, and MAT exports. These formats simplify reporting and further engineering analysis.
