Micro-amplitude vibration (amplitude ≤ 1μm, frequency 0.5-200Hz) is a core interference source in fields such as precision manufacturing and quantum scientific research.
Its harm is covert: ground micro-vibration may cause exposure deviations of up to 10nm in lithography machines, vibration in MRI equipment can induce imaging artifacts, and vibration in ultra-low temperature systems of quantum computers directly undermines the stability of quantum states.
Therefore, micro-amplitude vibration control has become the "technical cornerstone" for the stable operation of high-end equipment.
The LHV series active vibration isolation module launched by LeadTop achieves omnidirectional protection through three core technologies:
Air spring + single pendulum decoupling architecture: The Z-axis is vertically supported by an air spring, while the X/Y-axis is independently decoupled through a pendulum-style horizontal damping mechanism. This design enhances vibration attenuation efficiency by 40% compared to traditional structures, making it particularly suitable for equipment sensitive to vibration direction, such as laser interferometers.
Six-degree-of-freedom active control system: Integrating piezoelectric actuator arrays and 24-bit MEMS sensors, it achieves real-time compensation with ±2μm displacement accuracy and 0.001° angular deviation, meeting the ultra-quiet environmental requirements of 10-6g magnitude for atomic clocks, quantum computer ultra-low temperature systems, and other applications.
Wide-frequency domain composite protection: Combining Quasi-Zero Stiffness (QZS) vibration isolation and Magnetorheological Damping (MRD) technology, it covers a frequency band of 0.5Hz-2kHz, with an impact resistance capability of 25g@11ms, and has passed MIL-STD-810G military standard certification.
The LHV series is equipped with FPGA hardware-in-the-loop control technology, achieving a system response time of ≤8ms and a steady-state recovery period of <50ms. For instance, in lithium battery electrode coating machine applications, it can quickly suppress the impact vibration generated by equipment start-stop, preventing uneven coating thickness.In aerospace inertial navigation calibration platforms, even in the event of sudden vibration, it can maintain stability with an RMS value of <0.02g.
In addition, its intelligent load adaptation system can automatically recognize load changes ranging from 0.5 to 5 tons. Through coordinated adjustments of pneumatic PID pressure regulation and actuator gain, the stiffness adjustment range can reach 1:8, ensuring vibration isolation efficiency fluctuations of less than ±3% under different working conditions. This makes it the preferred solution in the global ultra-precision equipment vibration isolation field.
The LHV series has served over 500 high-end projects worldwide:
Acoustic Laboratory: Mitigating the impact of ground vibration on the uniformity of the sound field in the anechoic chamber;
Medical imaging: Eliminate mechanical vibration interference from MRI and CT equipment to enhance imaging resolution;
New energy manufacturing: Mitigate vibration defects in fuel cell bipolar plate imprinting equipment to enhance the yield of good products;
Precision metrology: ensuring nanometer-level measurement repeatability for coordinate measuring machines and white light interferometers.
With technological breakthroughs in the LHV series, LeadTop has become a core supplier of vibration isolation optical platforms and accessory products globally, continuously driving precision manufacturing towards higher accuracy.
