Engineering summary
QuakeLogic's Ironcore biaxial shake table pairs sub-1 mm-gap magnetic linear motors with PID control to deliver 2g at 50 kg, 125 mm stroke and 15 Hz on two axes.
In short: The Ironcore biaxial shake table achieves precise, low-friction motion because its magnetic linear motors drive the platform with no contact between motor and rail; the gap is under 1 mm and the only friction comes from the rail guards. It delivers 2g at a 50 kg payload, 125 mm stroke in each direction and up to 15 Hz on two lateral axes, with closed-loop PID control and EASYTEST software.
At QuakeLogic, we understand that precise and reliable seismic testing is crucial for advancing structural integrity and earthquake resilience. That’s why we’re proud to offer the state-of-the-art ironcore shake biaxial table, designed to meet the highest standards in the industry.
Why Choose the BI-AXIAL IRON CORE Shake Table?
Our ironcore shake table is equipped with cutting-edge linear motor technology, which uses magnetic forces to generate motion. Unlike traditional systems, there is no physical contact between the motor and the rail (gap is less than a 1 mm), resulting in minimal friction. The only friction comes from the rail guards, ensuring smoother, more accurate simulations. This advanced design provides the direct-drive precision and control necessary for high-fidelity testing, making it ideal for engineers and researchers on the forefront of structural testing.

Additional Accessories
Introducing the QL-MINI digital triaxial MEMS accelerometers and inclinometers combo sensor, designed for seamless integration with a Windows PC via USB. These sensors come with our complimentary QL-VISIO software, enabling real-time data analysis and retrieval with ease.
For enhanced demonstrations, we offer a modular plexiglass model structure specifically designed for use with the shake table. We recommend pairing this structure with five QL-MINI sensors to maximize the demonstration’s effectiveness.
Additionally, we provide a custom-made plexiglass box, known as the GEOBOX, ideal for geotechnical earthquake engineering demonstrations. This robust, waterproof box is perfect for simulating liquefaction, lateral spreading, slope stability, and more, and is designed for easy mounting on the shake table.

- A closed-loop PID controller executes custom and standard waveforms including sine sweeps on X, Y or both axes.
- EASYTEST software handles test setup, execution, real-time monitoring and data analysis.
- Accessories: QL-MINI USB triaxial MEMS accelerometer/inclinometer, plexiglass model structure and GEOBOX for liquefaction demos.
Frequently Asked Questions
The Ironcore biaxial shake table provides two lateral degrees of freedom, 2g acceleration at a 50 kg payload, a stroke of 125 mm in each direction and operation up to 15 Hz. Motion is produced by magnetic linear motors under closed-loop PID control, supports custom and standard waveforms, and is set up, executed and analyzed through QuakeLogic's EASYTEST software in a plug-and-play configuration.
In a magnetic linear motor there is no mechanical contact between the motor and the rail; the gap is less than 1 mm and magnetic forces generate the motion directly. The only friction in the Ironcore table comes from the rail guards, so there is no gearbox, belt or ball screw to introduce backlash or wear. The result is smoother, quieter and more accurate reproduction of the commanded waveform.
EASYTEST is QuakeLogic's proprietary control software integrated with the Ironcore shake table. It provides an interface for defining test parameters, executing sine sweeps, recorded earthquakes and custom waveforms, and monitoring the table in real time. It also handles data analysis so that a user can go from setup to consistent, repeatable results without separate control and acquisition tools.
QuakeLogic offers QL-MINI digital triaxial MEMS accelerometer and inclinometer combo sensors that connect to a Windows PC by USB and use the free QL-VISIO software; a modular plexiglass model structure, best instrumented with five QL-MINI sensors; and the GEOBOX, a waterproof plexiglass container that mounts on the table for liquefaction, lateral spreading and slope-stability demonstrations.
The institutions named as users of QuakeLogic shake tables include Nokia, Texas A&M, the University of Nevada Reno, UC San Diego, the University of Texas, Caltech, Imperial College, Virginia Tech and AUS. These users span industrial vibration testing and university earthquake engineering research and teaching, where quiet, repeatable two-axis motion matters.
