Sensitivity Simulation Analysis of Influencing Factors of Resonance Frequency of FDN Anti-vibration Hammer

Gale weather conditions always test the safety of the line, often lead to transmission line fatigue broken, or even broken phenomenon, can cause serious accidents. Therefore, in order to study the suppression of wind-induced vibration of conductors and ensure the stable operation of lines, this paper takes FDN type anti-vibration hammer as the research object, solves the vibration differential equation of anti-vibration hammer, and obtains the vibration mode and natural frequency of anti-vibration hammer. The ANSYS finite element method is used to model, and the natural frequency and vibration mode are calculated by modal analysis method. The reliability of the finite element model of the damper is verified by comparing the calculated values of the two models.
