Design of Anti-breeze Vibration for Long-wave Antenna with Large Span Conductor

The long-wave antenna is typically installed in land plains or valleys and the large span conductor is used as its radiator, which plays an important role in underwater communication. The wind load excitation with great destruction will cause vibration of the conductor, and then lead to fatigue damage, which will lead to broken strands, broken wires, metal joints rupture and failure. Study on the breeze vibration of long-wave antenna has not yet been reported. Starting with the cause of breeze vibration, in this paper the factors affecting the vibration of long-wave antenna wire are analyzed, and the anti-vibration design are carried out for a long-wave antenna with large span conductor combined with a practical project. The multi-mode combined anti-vibration method adopted in this paper is proved to be effective and the relevant experience can be used for the anti-vibration of the following long-wave antenna wire.
