What is active vibration isolation?

Active vibration isolation is a dynamic vibration control technology that uses sensors to monitor vibration signals in real time. The controller quickly calculates the reverse compensation force and the actuator performs the cancellation action, forming a closed-loop system of "monitoring analysis compensation". Its advantage lies in its ability to accurately suppress low-frequency vibrations (such as building shaking and personnel movement), while passive isolation has limited effectiveness on such vibrations.

Technical advantages of active vibration isolation

Compared to passive isolation, active isolation has three core advantages: firstly, it has a wide frequency band coverage and can handle vibrations ranging from 1-200Hz; Secondly, it has a fast response speed, with LeadTop's TA800 desktop active isolation table having a response time of only 10-20ms and completing dynamic leveling within 30 seconds; Thirdly, it has strong adaptability and supports fully automatic height adjustment and online modal analysis, meeting the dynamic needs of scenarios such as wafer inspection and quantum computing.

Typical Applications of Active Vibration Isolation

In the field of semiconductor testing, LeadTop's LVH-T15 heavy-duty active isolation platform achieves 500kg ultra large load capacity and 30ms step disturbance suppression through electromagnetic actuator and four stage air spring composite technology, significantly improving electron microscopy imaging resolution and FIB beam stability.

In the field of life sciences, its low-frequency attenuation is greater than 35dB@5Hz The characteristics provide a stable environment for cryo electron microscopy and other equipment, assisting in scientific breakthroughs.

summary

Active isolation achieves full frequency band vibration suppression through dynamic compensation, becoming a core technology in precision manufacturing and scientific research fields. LeadTop, with innovative products such as TA800 and LVH-T15, covers light to heavy load scenarios, providing a one-stop vibration control solution for high-end laboratory and industrial customers with high isolation efficiency, fast response, and intelligent adjustment capabilities.
