The portable bench-scale table represents a highly valuable resource for in-depth exploration of the effects of dynamic forces on structures, making significant contributions to the fields of structural dynamics, earthquake engineering, and civil engineering. Notably, this table possesses the ability to move along a single axis. Furthermore, when two tables are coupled together, it allows for dual-axis operation, specifically enabling precise x-y movement. This unit empowers trainers and researchers to conduct comprehensive investigations into the behavior of structures, including bridges, buildings, and various materials. By utilizing a diverse range of input signals such as sine waves, chirp signals, and scaled earthquakes, the table facilitates an accurate analysis of the impact these forces exert on the aforementioned structures.

  • The unit has a top stage that is powered by a strong motor that enables it to accelerate at 2.5 g when weighed down by a 7.5 kg mass.
  • The stage travels a total of 15.2 cm and is supported by two linear bearings mounted on ground-hardened metal shafts, enabling smooth linear motion with minimal path A deflection.
  • High-powered, three-phase brushless DC actuator with a 400 W output powers the simulator's motor.
  • The stage position may be measured with an effective linear resolution of 1.55 m thanks to a high-resolution encoder that is integrated into the motor.
  • The acceleration of the stage is directly measured by an analogue accelerometer fitted on the simulator platform.
  • For use with the shaker simulator, additional earthquake profiles can be downloaded from the PEER Ground Motion Database and scaled down.
  • Additionally, the bench-scale table offers the flexibility to couple two tables together, enabling dual-axis operation specifically for x-y movement.
  • The usage of two simulator systems allows users to work with larger payloads or conduct research with bi-directional shaking.
  • The simulator is equipped with a high-resolution encoder and a durable ball-screw actuation mechanism.
  • To drive powerful systems, the PWM amplifier, a single-channel pulse width modulated current amplifier.
  • The amplifier has a current detecting function and a standard data acquisition board interface.
  • The apparatus is user-built structures, external sensors, and external actuators are easily integrated.
