Active Vibration Isolation System

Active Vibration Isolation System

Active vibration isolation systems consist of a spring, feedback, and feed-forward control algorithm with vibration sensors and actuators. e feedback control algorithm uses sensors that continuously measure disturbance originating from a payload, and sends signals to the actuators to cancel out that disturbance. At the same time, the feed-forward control system uses measurements of external vibration for controller input, remarkably reducing floor vibration.

Active Vibration Isolation in Low Frequency

The passive vibration isolation system generally has its natural frequency 1.5 Hz to 10 Hz, allowing floor vibration transmitted and amplified in the low frequency range.
The active vibration isolation system overcomes the passive vibration isolation system’s weakness by lowering the natural frequency of the system down to the sub-hertz. Thus, the active vibration isolation systems do not suffer from resonance, effectively reducing the low frequency vibration. Our active vibration isolation systems starts to reduce vibration from 0.5 Hz, achieving 90% vibration isolation at 2 Hz.

Six Degrees of Freedom

Sensors and actuators that are integrated in the active vibration isolation system, control vibration in three translation degrees of motions (X, Y and Z), and three rotational degrees of motions (Pitch, Roll and Yaw).
