Ironcore Biaxial Shake Table with Magnetic Motors: Precision and Power in Vibration Testing

iron core 1 for "Electro Servo Motors or Linear Motors for Shake Tables: Choosing the Right Technology"

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.

If you want to learn more about the linear motor technology, read our blog HERE.


Key Features of IRONCORE BIAXIAL shake table:

  • Bi-Axial Motion: Two lateral degrees of freedom for comprehensive testing.
  • High Capacity: ± 2g at 50 kg, with a stroke of ±125 mm and up to 15 Hz operational frequency.
  • Precision Control: Closed-loop PID system ensures exact motion execution.
  • Magnetic Linear Motors: No contact between motor and rail, reducing friction and wear.
  • Versatile Waveforms: Supports custom and standard waveforms for diverse testing scenarios.
  • Plug & Play Design: Easy setup, high reliability, and minimal maintenance.
  • EASYTEST Software: The ironcore shake table is integrated with our proprietary EASYTEST software, offering an intuitive interface for test setup, execution, and data analysis. EASYTEST simplifies complex testing procedures, enhances workflow efficiency, and provides comprehensive real-time monitoring and control, making it easier than ever to achieve accurate and consistent results.

Executive Summary

Earthquake engineering connects ground motion, structural response, performance objectives, instrumentation, and post-event decision support. This article has been expanded as an engineering resource for readers evaluating earthquake engineering 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 earthquake engineering 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

ApplicationEngineering QuestionTypical Evidence Needed
Research and educationHow does a structure, component, or sensor respond under controlled conditions?Test plan, calibrated data, input motion, boundary conditions, and repeatable observations.
Critical infrastructureIs the asset response normal, changing, or potentially unsafe after an event?Baseline data, event records, thresholds, inspection workflow, and engineering sign-off.
Industrial facilitiesCan 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.
