Research on Galloping Suppression of Iced Conductors Based on Suspended Tuned Mass Damper
finite element models of both single and six-bundle conductor lines are established to analyze their galloping response characteristics. To suppress galloping
a control strategy based on a suspended tuned mass damper(TMD) is proposed. Based on the ANSYS finite element platform
refined finite element models of a single conductor and a six-bundle conductor are established respectively to simulate and analyze the entire galloping process. Key damper parameters are designed in accordance with modal analysis results and the theory of TMD parameter optimization. By studying the influence of TMD placement strategies-single-point
two-point
and three-point arrangements at the mid-span and quarter-points-as well as the mass ratio
it is found that the three-point configuration most effectively suppresses galloping across the entire line. When the mass ratio is 2%
basic galloping suppression can be achieved
and the suspension TMD scheme has a significant effect on galloping suppression performance.
