Shake Table I-40
Desktop simulator for structural dynamics modelling and control
The Quanser Shake Table I-40 is an open architecture 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.
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 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. The high-resolution encoder enables the system to obtain a linear stage position resolution of 1.22 μm.
