摘要
在系统分析舞动机理的基础上 ,通过对ADINA程序进行改造 ,并加入空气动力模块 ,开发了一套较为完整的输电导线舞动的计算机仿真程序 ,并利用该程序对大跨越输电线路的舞动形成过程及几种防舞器的防舞效果进行了动态仿真 ,通过与现场观测数据进行比较 。
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.
