Overview

IronCore Bi-Axial Shake Table is a complete research-grade earthquake simulation platform for laboratories that need accurate, repeatable two-axis ground motion reproduction. It is not simply a table that moves in two directions; it combines a biaxial linear-motor shake table, closed-loop motion control, operating software, feedback instrumentation, and QuakeLogic engineering support in one turnkey seismic testing system.

The system is designed for university earthquake engineering programs, structural dynamics laboratories, geotechnical research groups, sensor developers, and teaching labs that need controlled experiments with low mechanical noise, strong repeatability, and reliable waveform tracking.

Why the IronCore System Is Different

Conventional shake tables often rely on rotary motors, gearboxes, belts, ball screws, hydraulic actuators, or other mechanical transmission components to convert motor rotation into linear motion. Those components can add friction, backlash, vibration, bearing noise, wear, calibration drift, and reduced accuracy during direction reversals.

The IronCore system uses magnetic linear-motor drive technology to generate motion directly at the moving platform. With fewer mechanical power-transmission elements between the actuator and the table, the system is built to reduce friction, backlash, vibration noise, and waveform distortion. The result is a cleaner, more precise motion platform for reproducing earthquake records, sine waves, sweeps, random signals, pulses, and user-defined waveforms.

Motion Accuracy for Publishable Research

For serious seismic research, the key question is not whether a model visibly shakes. The question is whether the platform can reproduce the requested acceleration, velocity, displacement, phase, frequency content, and synchronized biaxial motion with confidence. IronCore is designed around closed-loop control, accurate direction changes, smooth low-amplitude movement, low mechanical noise, reduced cross-axis interference, and consistent performance across repeated tests.

This matters for structural response studies, soil testing, liquefaction experiments, base-isolation research, vibration-control development, sensor validation, and comparative laboratory experiments where repeatability and traceable motion quality are essential.

True Biaxial Earthquake Simulation

Real earthquake motion does not act in only one horizontal direction. IronCore can apply controlled simultaneous motion in two horizontal axes, helping researchers study coupled X/Y response, torsion, multi-axis structural behavior, soil-structure interaction, and sensor performance under more realistic seismic inputs.

Turnkey Laboratory Platform

QuakeLogic delivers the IronCore system as an integrated laboratory solution: biaxial shake table, motion controller, closed-loop feedback system, control electronics, user-friendly operating software, earthquake-record playback, custom waveform generation, sensor and data-acquisition compatibility, technical documentation, remote commissioning, training, and ongoing engineering support.

The operating workflow is built so users can import earthquake records, define test parameters, run the table, monitor the experiment, and repeat the same test under consistent conditions without building a motion-control stack from the beginning. This reduces setup time for teaching labs while preserving the capability needed for graduate and faculty research.

Long-Term Value

The IronCore package includes no annual software licensing fee, no recurring controller subscription, lifetime software updates, lifetime technical support, remote engineering assistance, and support for future accessories and experimental configurations. The linear-motor architecture also reduces wear points compared with systems based on belts, gears, screws, or hydraulic mechanisms, supporting lower maintenance requirements, less downtime, quieter operation, and stable long-term laboratory performance.

Applications

  • Earthquake engineering education and research
  • Structural dynamics and multi-axis response studies
  • Soil-structure interaction and geotechnical model testing
  • Liquefaction, slope-stability, and landslide demonstrations
  • Base-isolation and tuned-mass-damper studies
  • Structural-health-monitoring and sensor validation
  • Vibration-control and control-system development
  • Senior design, master’s, doctoral, and faculty research projects

Why Choose QuakeLogic

QuakeLogic helps universities move from equipment purchase to working experiments. The value is not only the table size; it is the combination of motion-control accuracy, biaxial synchronization, waveform reproduction, research software, instrumentation compatibility, safety-aware operation, documentation, training, and long-term engineering support. For labs comparing a basic fabricated motion platform with a complete earthquake-simulation laboratory, IronCore is the premium turnkey choice.

Recommended Turnkey Configuration

For programs building a full structural and geotechnical teaching and research lab, QuakeLogic can configure an upgraded package around the 75 x 75 cm IronCore platform with motion-control hardware, QuakeLogic waveform-reproduction software, feedback instrumentation, structural demonstration models, liquefaction and slope-stability modules, displacement transducers, pore-water-pressure sensors, accelerometers, multichannel data acquisition, signal conditioning, educational experiment materials, export packing, shipping support, remote commissioning, training, lifetime technical support, and lifetime software updates.
