Uniaxial Shake Table
The BI-7300 Uniaxial Shake Table is a high-precision, servo-hydraulic vibration simulation platform engineered for single-axis dynamic testing of structures, components, and geotechnical models. Designed to replicate realistic seismic and vibration environments, this system provides controlled displacement, velocity, and acceleration profiles using programmable waveforms.
Built with a rigid, self-reacting structure, the table eliminates the need for grouting or external foundations. Its high-force actuator, robust platform design, and real-time digital control system make it an essential tool for earthquake engineering research, structural dynamics testing, and component qualification in both industrial and academic settings.
With a displacement range of ±125 mm (or customizable), high sampling rate up to 10 kHz, and intuitive control software, the BI-7300 delivers repeatable, accurate, and standards-compliant test results for a wide range of vibration and seismic simulation applications.
