QL – Uniaxial Servo-Electric Shake Table | 2-Ton Capacity | 4.5 m × 1.5 m
The QL Uniaxial Servo-Electric Shake Table is a high-precision dynamic and seismic testing system designed for large structural specimens. With a 2-ton payload capacity, 4.5 m × 1.5 m aluminum table, and servo-electric drive, it delivers accurate, repeatable, and energy-efficient uniaxial motion for laboratory and academic research applications.
OVERVIEW
Description
The QL – Uniaxial Servo-Electric Shake Table (2-Ton, 4.5 m × 1.5 m) is engineered for dynamic response analysis, seismic simulation, and vibration testing of large-scale specimens. In addition, it utilizes a high-precision servo-electric drive system. As a result, the table achieves up to 1 g acceleration and peak velocities of 1,000 mm/s. It maintains exceptional motion accuracy.
The system features a precision-ground roller screw actuator, low-friction linear guides, and a rigid aluminum test table. The table is optimized for flexible specimen mounting. It operates over a 0.1–15 Hz frequency range with a ±200 mm stroke. Therefore, the shake table is ideal for structural engineering research, academic laboratories, and seismic performance evaluation.
Advanced single-axis motion control and integrated earthquake simulation software enable accurate reproduction of recorded time histories and frequency sweeps. They also support custom waveform profiles. Moreover, comprehensive safety systems and digital monitoring ensure reliable and secure operation during high-energy testing.
