An electromagnetic shake table is now a critical asset for modern structural dynamics and earthquake engineering laboratories. Traditionally, academic institutions and research facilities faced a massive challenge because large-scale simulator systems required extensive infrastructure, huge power demands, and high operational budgets. Fortunately, achieving precise, high-fidelity seismic simulations within a restricted laboratory space is now completely accessible.

To bridge this structural testing gap, QuakeLogic proudly introduces the compact QL-ATOM 25 Electromagnetic Shake Table System. This high-performance desktop laboratory solution delivers exceptional accuracy, absolute repeatability, and reliable dynamic testing for universities and engineering firms worldwide.

Precision Engineering via Electromagnetic Shake Table Technology

At the absolute core of the QL-ATOM 25 is a digital closed-loop servo motion control system that works seamlessly with an advanced electromagnetic actuator. Unlike conventional hydraulic options that demand complex fluid maintenance and create constant leakage risks, this system ensures clean, silent, and entirely maintenance-free operations.

Furthermore, by utilizing precision linear guide rails and a high-resolution encoder for continuous position feedback, this dynamic platform guarantees unmatched positioning accuracy. Consequently, researchers can perform micro-level adjustments during sensitive experiments.

Key Technical Capabilities:

• Generous Stroke Capacity: A total displacement range of $\pm125\text{ mm}$ allows for comprehensive dynamic movements.
• Broad Operating Frequency: The system delivers exceptionally accurate motion profiles from DC up to $30\text{ Hz}$.
• High Acceleration Peak: It easily reaches up to $1\text{ g}$ of peak acceleration while supporting a maximum payload capacity of $50\text{ kg}$.

Versatile Testing Modes and Software Capabilities

The QL-ATOM 25 electromagnetic shake table supports a comprehensive array of complex testing protocols. Operators manage every single simulation via the intuitive EasyTest Shake Table Control Software. Therefore, users can configure, execute, and monitor multiple specialized excitation modes with just a few clicks:

• Sine Excitation & Frequency Sweep: These options help identify natural frequencies, extract damping ratios, and validate structural mode shapes during structural dynamics and modal analysis.
• Random Vibration Control: This profile effectively simulates real-world environmental ambient vibrations to evaluate material fatigue and long-term structural durability.
• Earthquake Replay: The software replicates historical seismic events by using actual recorded acceleration data, which provides an indispensable tool for advanced earthquake engineering research.
• User-Defined Motion Profiles: This capability grants research teams full creative control because they can upload custom displacement or acceleration waveforms effortlessly.

Integrated Data Acquisition and Enhanced Laboratory Safety

Data integrity and student safety remain critical priorities in any structural testing facility. For this reason, the QL-ATOM 25 includes a robust integrated data acquisition system that monitors displacement, velocity, acceleration, and frequency in real time. Because the software automates data logging, it generates professional, printable test reports instantly.

In addition, users can effortlessly export all experimental data into widely utilized formats, including CSV, TXT, and MATLAB-compatible files for deep post-test analytical evaluation. Consequently, you can review the complete structural dataset and comprehensive technical layout directly through the integrated system software dashboard.

Safety is maintained at the highest level through a multi-layered hardware and software protection suite. The structural testing platform includes an easily accessible emergency stop button, physical hardware limit switches, automated software motion limits, overcurrent protection, and automatic fault shutdown procedures. As a result, the machinery guarantees safe operation under all circumstances.

Empowering Engineering Education and Precision Calibration

Beyond advanced institutional research, the compact footprint and plug-and-play design make the QL-ATOM 25 perfect for university classrooms. It operates reliably on a standard 110-240 VAC single-phase power supply. Consequently, it allows civil engineering students to witness structural behavior, resonance, and seismic mitigation strategies firsthand.

Furthermore, due to its high precision, technicians can utilize the system as an official calibration bench for external accelerometers and delicate seismic instruments.
