Abstract: The parameter analysis was presented for continuous spans vibration induced by single-span conductor galloping. The fine finite element model of continous spans and insulator strings was set up by ABAQUS softwart, the aerodynamic load was defined by UEL. So the dynamic response of continuous spans induced by single-span conductor galloping were numerically simulated in ABAQUS. The numerical simulation results show that the structure parameters have obvious effect on the vibration amplitude of the displacements and tention, low order modes have great influence on the vibration amplitede of the displacements, high order modes have great influence on the vibration amplitude of the tention. The galloping damage can be reduced in transmission line design using the conclusions of parameter analysis. The conclusion is a useful reference for anti-galloping of continuous spans.

Key words: galloping, finite element, continuous spans, transmission line conducto
