The Quanser Shake Table II is a mid-size, open architecture, single-axis motion simulator ideal for teaching and doing research in structural dynamics, earthquake engineering, and other topics related to structural, earthquake, and civil engineering. Users can apply sine waves, chirp signals and scaled earthquakes, such as the Northridge, Kobe, and El-Centro supplied, to study their effects on buildings, bridges, and various materials. Additional earthquake profiles can be downloaded from the PEER Ground Motion Database and scaled down for replaying on the Shake Table II. By combining two Shake Table II systems, users can perform bi-directional shaking experiments, or work with higher payloads.
