University of Washington Receives Next-Gen Seismic Testing Technology from QuakeLogic: engineering guidance from QuakeLogic covering shake tables, appli...
QuakeLogic is proud to deliver its next-generation Ironcore Bi-Axial Shake Table to the University of Washington—powered by magnetic linear motors, making it the quietest, most precise, and most efficient biaxial shake table on the market today.
This state-of-the-art system joins an elite lineup, including a recent deployment at CALTECH, and is designed to elevate seismic education and research across leading academic institutions.
To further enhance the hands-on learning experience in structural dynamics, we also provided a 6-story modular plexiglass model structure. This tool enables students to directly observe and analyze real-time structural behavior under simulated earthquake loading, making abstract theory visible and tangible.
Key Features of the IRONCORE Bi-Axial Shake Table:
👉 Bi-Axial Motion – Two lateral degrees of freedom for complex seismic testing
👉 High Capacity – ±2g acceleration at 50 kg (or ±1g at 100 kg), ±125 mm stroke, up to 15 Hz frequency
👉 Magnetic Linear Motors – Frictionless, ultra-quiet, and low-maintenance performance
👉 Closed-Loop PID Control – Precision motion tracking and waveform fidelity
👉 Versatile Inputs – Supports both standard and custom seismic waveforms
👉 Plug & Play – Easy setup, operation, and industrial-grade reliability
👉 EASYTEST Software – Streamlined test setup, real-time monitoring, and data analysis
- Built to advance education.
- Designed to accelerate research.
- Engineered for real-world seismic simulation.

Executive Summary
Shake tables reproduce controlled motion in the laboratory so engineers can evaluate components, assemblies, soil boxes, and structural models under seismic inputs. This article has been expanded as an engineering resource for readers evaluating shake tables concepts, instrumentation choices, and monitoring workflows. The discussion is educational and should be paired with project-specific review by qualified engineers, applicable codes, owner requirements, and equipment documentation.
Key Takeaways
- Define the engineering objective before selecting sensors, test equipment, trigger thresholds, or reporting workflows.
- Use calibrated instrumentation, documented installation practices, time synchronization, and traceable data handling where measurement quality matters.
- Interpret measured data in context: site conditions, structure type, noise environment, sampling rate, bandwidth, and boundary conditions all affect conclusions.
- Use authoritative references and project-specific criteria rather than relying on generic thresholds or unsupported performance claims.
Technical Explanation
In practical shake tables work, the engineering system is more than a sensor or a test platform. A credible workflow includes the measurement objective, instrument selection, mounting or boundary conditions, sampling and timing strategy, data validation, event or response detection, engineering review, and reporting. Weakness in any part of that chain can reduce confidence in the final interpretation.
For monitoring applications, engineers should document sensor orientation, coupling, environmental exposure, dynamic range, frequency bandwidth, data logger configuration, clock synchronization, communications, and maintenance procedures. For testing applications, engineers should document input motion, fixture design, payload properties, control limits, safety interlocks, acceptance criteria, and post-test data review.
Engineering Applications
| Application | Engineering Question | Typical Evidence Needed |
|---|---|---|
| Research and education | How does a structure, component, or sensor respond under controlled conditions? | Test plan, calibrated data, input motion, boundary conditions, and repeatable observations. |
| Critical infrastructure | Is the asset response normal, changing, or potentially unsafe after an event? | Baseline data, event records, thresholds, inspection workflow, and engineering sign-off. |
| Industrial facilities | Can monitoring support operational continuity and response decisions? | Site-specific criteria, reliable telemetry, alarm logic, maintenance records, and documented procedures. |
People Also Ask
What should be specified before buying equipment?
Specify the measurement objective, frequency range, amplitude range, environment, data format, timing needs, installation constraints, reporting requirements, and applicable standards or owner criteria.
Why do references and standards matter?
They provide terminology, acceptance criteria, test methods, and documentation expectations. They do not replace engineering judgment, but they reduce ambiguity and make results easier to review.
How should data quality be checked?
Review calibration status, timing, clipping, sensor orientation, signal-to-noise ratio, environmental artifacts, data completeness, and whether the record supports the engineering decision being made.
