| Abstract: | Based on the galloping mechanism, the computer simulation of power line galloping by using the nonlinear finite element method and the calculation of air dynamic forces are presented. By using the modified ADINA program and the air_dynamic_forces module, the authors develop a set of software named computer simulation of power line galloping. With the comparison between the result of simulation and the observed data, it shows that the nonlinear finite element method is effective and correct for analyzing galloping of power lines. |
