A new anti-vibration hardware, that is, the damping spring spacer of vibration and dance reduction has improved the method of traditional hardware fittings in vibration reduction, adopting the joint vibration reduction of damping spring and heavy ball to keep down breeze vibration in the transmission lines. The quite big innovation has achieved on the components and structure form of new anti-vibration hardware by forming spacer framework, damping spring, and heavy ball as a whole. For obtaining the effect of vibration reduction, the vibration energy is dissipated through the constant movement of damping spring and heavy ball. The finite element software of ANSYS is used to build conductors on a quad bundled model equipped with spacer to simulate breeze vibration. By comparing the curves of displacement process in the cases of no conductor spacer, ordinary conductor spacer, and damping spring spacer of vibration and dance reduction, respectively, it is known that the strengths of the new anti-vibration hardware in vibration reduction, i.e. damping spring spacer of vibration and dance reduction is able to decrease the maximum amplitude of the conductor to the minimum at the same time. Conductor spacer parameter with optimal vibration reduction performance is obtained by nonlinear fitting and parameter optimization. ANSYS is used to verify optimal data, and finally found that when the quality of heavy ball is 1.8kg and the stiffness of spring is 0.7kN/m, damping spring spacer of vibration and dance reduction is able to achieve the optimal effect of vibration reduction.
