The air flotation vibration isolation platform is a precision equipment that uses compressed gas (air or nitrogen) as a support and isolation medium. The core isolates environmental vibrations through gas springs and damping systems, providing a stable working surface for high-precision scenarios. It is widely used in scientific research and industrial fields. Core conclusion: The mainstream is divided into passive and active types. Passive type is preferred for conventional scenarios (high cost-effectiveness, easy maintenance), while active type is preferred for nanometer level precision or harsh vibration environments (higher isolation efficiency); The selection core focuses on three major indicators: natural frequency, load-bearing capacity, and table accuracy.
The maintenance of the air flotation isolation platform should focus on the air source system, air flotation bearings, seals, and environmental cleanliness, including daily checks of air pressure, regular lubrication, and replacement of aging components.
The air flotation isolation platform forms a stable air film between the platform and the foundation through high-pressure air, and utilizes the air static pressure effect to achieve suspension and isolation. The specific process is as follows:
Formation of gas film: Compressed gas is injected into the dedicated gas chamber between the platform and the base to form a uniformly distributed thin gas film, which separates the platform body from the solid contact with the base and greatly weakens the vibration transmission efficiency.
Parameter regulation: Equipped with an air pressure regulation module, it can accurately regulate the stiffness and damping parameters of the gas film according to the isolation requirements of different devices such as electron microscopes and laser interferometers, achieving customized vibration control.
Displacement compensation: Some models integrate high-precision displacement monitoring and compensation systems, which capture small posture changes of the platform in real time through sensors, and work with pneumatic or electric actuators to quickly correct displacement deviations, further improving operational stability.
Application scenarios
The application scope of air flotation vibration isolation platform is constantly expanding, and it has been applied to three major fields:
In the field of scientific research experiments, it is used to isolate laboratory ground vibrations and surrounding equipment noise in experiments such as quantum entanglement observation, atomic force microscopy detection, and precision optical component calibration, ensuring the accuracy and repeatability of experimental data and providing a stable environment for scientific research.
Medical and aerospace fields: In high field magnetic resonance imaging equipment and precision testing instruments for aerospace components, vibration isolation is used to ensure the stability of equipment operation and meet the requirements of high-resolution medical imaging and precision testing of aerospace components.
In the field of precision manufacturing, we ensure machining accuracy and avoid machining errors caused by vibration interference in equipment such as lithography machines, wafer inspection equipment, and machining centers.
