AI Technical Summary

Technical Problem

Existing electromagnetic damping vibration isolation devices have a fixed magnetic field strength, which cannot adapt to complex vibration environments. Furthermore, coil heating leads to performance degradation, affecting the stability and reliability of the device.

Method used

The system employs coil assemblies arranged in a relatively opposite manner. By adjusting the direction and magnitude of the current, the strength and direction of the magnetic field are changed. It is combined with water-cooled pipes and heat sinks for cooling. The damping force is adjusted using wires of different diameters, forming a dual magnetic field coupling to dynamically adjust the damping force.

Benefits of technology

It enables flexible adjustment and precise control of the damping force, improves the adaptability and lifespan of the device, avoids performance degradation caused by coil overheating, and ensures the stability of the magnetic field.
