摘要 超长输电线由于风力作用会产生涡激振动,危及导线正常工作。一般采用在导线特定位置安装阻尼防振锤的方法来减小导线的振幅,改善振型,计算导线系统的自由振动是研究微风防振的关键。采用积分变换法计算系统的自由振动,具有计算量小,振型表达式完整明确的优点。 Vortex-induced vibration of over-head transmission line endanger the strand of conductor. The natural vibration of the line is usually calculated by transfer-matrix method. A integral alternate method is introduced to answer the natural vibration.
