The Quanser Shake Table I-40 is a bench-scale single-axis earthquake simulator ideal for teaching structural dynamics and control, earthquake engineering and other control topics related to civil engineering. With pre-loaded acceleration profiles of real earthquakes, such as Northridge and El-Centro, students can study their effects on buildings, bridges and various materials. As a typical application, the Shake Table I-40 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:
Shake Table I-40 has been also used in outreach programs involving community services and K-12 education.
Create a Configuration That Suits your Needs
You can expand the Shake Table I-40 experiments by adding the Quanser One-floor Active Mass Damper structure to create new MIMO experiments. Also, additional earthquake acceleration profiles can be downloaded from the PEER Strong Motion website.
How It Works
The Shake Table I-40 consists of a stage mounted on a high-quality, low backlash linear guide with a total travel of 40.0 mm (i.e., ± 20.0 mm) and is driven using a ball-screw drive mechanism. Using the high torque direct drive motor, the stage loaded with a 1.5 kg mass can be accelerated up to 1.0 g (i.e., 9.81 m/s²). The high-resolution encoder enables the system to obtain a linear stage position resolution of 1.22 μm.
The Shake Table I-40 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.
The Quanser Shake Table I-40 experiment comes with Quanser-developed courseware. The Laboratory Guide together with a comprehensive User Manual, 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.
