Shake Table II
The Quanser Shake Table II is a mid-size open-architecture single-axis earthquake simulator ideal for teaching structural dynamics, vibration isolation, feedback control, and other control topics related to earthquake, aerospace and mechanical engineering. Users can generate sinusoidal, chip as well as pre-loaded acceleration profiles of real earthquakes, such as Northridge, Kobe and El-Centro, to study their effects on buildings, bridges and various materials. Additionally, earthquake profiles can be downloaded from the PEER Ground Motion Database, scaled using the supplied software, and replayed on the Shake Table II.
