Definitions of Active and Passive Vibration Isolation

Vibration isolation is a technology that blocks or attenuates the transmission of vibrational energy, categorized into active and passive approaches. Passive isolation relies on materials or structures to absorb vibrations passively, while active isolation employs sensors and actuators to monitor vibrations in real time and counteract them dynamically, forming a closed-loop control system.

Passive Vibration Isolation: Static Defense Where Structure Reigns Supreme

Passive isolation centers on solid-state structures, exemplified by LeadTop's POT-P Series solid-state optical platforms. These utilize honeycomb/superparamagnetic base plates combined with shear-type rubber structures to suppress surface resonance through broadband damping. With vertical/horizontal natural frequencies of 6.5–12 Hz, it suits low-vibration applications like microscopy and medical biology but cannot handle sudden low-frequency disturbances.

Active Vibration Isolation: Intelligent Dynamic Countermeasures

Represented by the LHV series modules, active vibration isolation achieves six-degree-of-freedom precision control through air spring + pendulum decoupling design. It delivers ≤-30dB low-frequency vibration transmission (0.5-20Hz) and an 8ms response time to counteract transient impacts. Its intelligent load adaptation (0.5-5 tons) and ±2μm displacement compensation meet nanometer-level precision demands in quantum research and medical imaging.

Differences Between Active and Passive Vibration Isolation

Passive isolation offers simple structure and low maintenance but has limited low-frequency performance. Active isolation provides strong dynamic response and handles complex vibrations but carries higher costs. LeadTop's POT-P series and LHV modules cover mid-low and high-frequency scenarios respectively, allowing users to select solutions based on equipment vibration sensitivity.

Both active and passive isolation offer distinct advantages, requiring selection based on equipment requirements, budget, and environmental vibration characteristics. As a specialized supplier, LeadTop provides comprehensive solutions spanning passive POT-P platforms to active LHV modules, ensuring stable operation for scientific research and industrial equipment.
