The Quanser XY Shake Table III is a high-powered planar earthquake simulator ideal for more advanced dynamics and multidynamics analysis and research relating to earthquake loss reduction. It is capable of moving high loads of up to 100 kg at high accelerations and velocities.
With pre-loaded acceleration profiles of real earthquakes, such as Northridge and El-Centro, you can study their effects on buildings, bridges and various materials. As a typical application, the XY Shake Table III can excite the flexible modes of a tall structure in order to design, implement, and evaluate a control system to manipulate and dampen the structural vibrations. Students learn how to:
Additional earthquake acceleration profiles can be downloaded from the PEER Strong Motion website.
The XY Shake Table III offers a wide table-top surface which can accommodate several structures, such as Quanser 1 Floor and 2 Floor Active Mass Dampers, to increase the complexity of the experiment.
How It Works
The Quanser XY Shake Table III consists of a stage mounted on the ground support plate. The stage can move in either the x or y directions and has a total travel more than 20 cm on each axis. Experimental structures can be attached to the stage to perform experiments.
To minimize the amount of moving parts and achieve optimal performance, the table is actuated using three linear motors. This increases the reliability of the system and keeps the operation of the system quiet. Two motors, mounted on the ground support plate of the table, operate in parallel and power the x-axis. A single motor mounted to the stage actuates the y-axis. Together the motors allow for XY planar motion in the Cartesian arrangement.
The displacement and acceleration of the stage are measured by the on-board encoder and the accelerometer sensors. The encoder and accelerometer are connected to the DAQ and their signals can be displayed and processed further. Plotted data can be also be saved for later analysis.
The XY Shake Table III can be easily programmed through a Graphical User Interface environment. The provided software eliminates any need for hand coding while enables to monitor and analyze the response. For a more flexible operation and control design, you can use MATLAB®/Simulink® via QUARC®.
The complete turn-key system comes with 230 V AC power system and rack-mount PC.
The Quanser XY Shake Table III system comes with Quanser-developed courseware. The comprehensive User Manual with experiments, pre-designed controllers and a dynamic model allow you to get your lab running faster, saving months of time typically required to develop lab materials.
