摘要
失谐摆是一种基于扭振激发机理的有效防舞动装置,导线运用失谐摆来调整扭振固有频率ft,使之与横向振动的高阶固有频率fvn分离,从而防止其耦合而诱发舞动。失谐摆对提高导线系统扭振固有频率的作用取决于它在导线上的配置,主要讨论了多种舞动波型的多种配置方式。
Detuning pendulum is an effective anti-galloping installation, which based on torsional vibration excitation mechanism. In order to isolate the conductor with the top horizontal natural freqtiency of vibration, using detuning pendulum to adjust the natural frequency of the torsional vibration in conductor, so it can reach the goal that prevents the coupling induced galloping. The improvement of detuning pendulum to the frequency torsional vibration of the wire system depends on their configuration on the conductor. This paper discusses a range of installed positions of the galloping waves.
