摘要

Existing vibration damping devices demonstrate poor adaptability to complex terrains and micro-meteorological conditions, failing to meet the requirements of contemporary super-large-span transmission projects. This paper proposes a zero-frequency vibration absorber incorporating nonlinear energy sinks (NES). Through power characteristic optimization experiments, key parameters such as the peak points of energy dissipation curves are analyzed to determine optimal nonlinear stiffness values. The design enhances damping characteristics and resonance capacity, improving vibration energy conversion and dissipation efficiency. The spring-oscillator structural configuration is further refined to address practical engineering demands for long-span transmission lines. Compared with conventional absorbers, the proposed solution achieves 23% mass reduction while maintaining equivalent energy dissipation capacity, significantly improving functional performance and effectiveness. This advancement provides critical technical support for enhancing transmission line wind resistance.
