Vibration control is a core requirement in precision manufacturing, scientific research, and experimental fields. Active and passive vibration isolation technologies, as the two mainstream solutions, achieve vibration energy attenuation and cancellation through different principles.

Passive Vibration Isolation: A “Low-Cost Barrier” Against High-Frequency Vibrations

Passive vibration isolation absorbs vibrational energy through mechanical structures like springs and dampers, requiring no external energy input. It offers advantages such as simple structure and easy maintenance.

Active Vibration Isolation: The “Smart Solution” for Low-Frequency Micro-Vibrations

Active vibration isolation employs sensors to monitor vibration signals in real time. After processing by a controller, actuators generate counteracting forces to form a dynamic compensation closed-loop system. Its core value lies in the ability of the active isolation system to control vibration displacement to the sub-nanometer level through electromagnetic actuators and adaptive algorithms, ensuring chip line width precision.

LeadTop's LHV Series Active Vibration Isolation Modules employ six-degree-of-freedom precision active control to achieve a low-frequency vibration transmission ratio ≤ -30dB at 0.5-20Hz, with an 8ms fast response time. They support ±2μm displacement compensation and intelligent load adaptation (0.5-5 tons). Suitable for high-precision applications such as acoustic laboratories, medical imaging, and quantum research.

From passive isolation's “economical defense” to active isolation's “intelligent counterattack,” these two technologies—through scenario-specific adaptation and collaborative innovation—jointly propel precision manufacturing toward nanometer-level accuracy.
