What is the vibration isolation principle of the vibration isolation table?

1. Active vibration isolation technology: The vibration isolation table usually uses active vibration isolation technology, which means that it will monitor the external vibration in real time through the built-in sensor. Once vibrations are detected, the control system responds immediately, applying a counterforce to the desktop through the actuators to counteract these vibrations. This kind of active control method can reduce the influence of vibration on experiment or work more effectively.

2. Multi-layer vibration isolation structure: The vibration isolation table is usually composed of a multi-layer structure, including an upper test or work platform, a vibration isolation layer in the middle and a support system in the lower part. This design helps to decrement and disperse external vibrations layer by layer, further reducing the amount of vibration energy transmitted to the table top.

3. High-precision control system: The vibration isolation table is equipped with a high-precision control system, which can monitor the position and vibration of the desktop in real time, and precisely adjust the working state of the actuator to maintain the stability and accuracy of the desktop. This control system is the key to the effective operation of the vibration isolation table.

4. Elastic or damping device: In the design of the vibration isolation table, elastic or damping devices are also used to link the vibration source and the table, so that most of the energy generated by the vibration source is absorbed by these devices, thereby reducing the interference of vibration on the table.

In summary, the vibration isolation principle of the vibration isolation table is through the comprehensive application of active vibration isolation technology, multi-layer vibration isolation structure, high-precision control system and elastic or damping device and other technical means to effectively reduce the interference of external vibration on the desktop and its equipment, to provide a more stable and accurate working or experimental environment.
