The Quanser Active Mass Damper (AMD) is a bench-scale model of a tall building equipped with an active damper. It is ideal for studying the dynamic response of tall structures to high winds, seismic ground effects, and other disturbances, and for investigating control techniques to actively dampen the deflection of structures.
The damper consists of a motorized linear cart instrumented with an encoder measuring the cart’s displacement. Additionally, the structure is instrumented to measure floor acceleration.
The Quanser Active Mass Damper is available in three different configurations: one-floor AMD, two-floor AMD with a single active cart, and two-floor AMD with two active carts. The structures can be mounted on the Quanser Shake Table I-40 (one-floor AMD) or Shake Table II (one- or two-floor AMD).
The Active Mass Damper (AMD) plant consists of a building-like structure with a controllable linear cart on the top. The cart is driven by a high-quality DC motor through a rack and pinion mechanism. The AMD frame is made of aluminum and is flexible along its facade. The top floor is instrumented with an accelerometer to measure the acceleration of the “roof” relative to the ground. The cart position is directly measured using an encoder. The encoder shaft meshes with the track via an additional pinion. Two masses can be attached to the cart to increase its inertia to absorb vibrations of the structure. The masses can be used individually, together or can be removed to assess the robustness of the controller and effects of variations in parameters.
The following additional components are required to complete your workstation, and are available separately:
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.
The Hexapod stands as a compact and robust six degrees of freedom parallel robotic motion platform, capable of high-acceleration movement handling up to 100 kg. Distinguishing itself from conventional Stewart platforms, this Hexapod utilizes advanced electrical motors, ensuring precision, responsiveness, and minimal maintenance.
The Shake Table II XY consists of two single-axis Shake Table II units mounted perpendicularly on top of each other. Each stage can travel ±7.6 cm. Driven by powerful motors, the Shake Table II XY can achieve an acceleration of 2.5 g when loaded with a 7.5 kg mass.
