Analysis of Guyed Transmission Tower Dynamic Characteristic

Abstract:

In the paper aiming at lots of 87(LM21) towers in Dongchang Hasong Transmission Line held under Changchun Extra-high voltage Bureau jurisdiction, by using ANSYS software, the nonlinear finite element model for towers is built. And numerical analysis methods is adopted. It is considered that the combined effect of stay wire and transmission tower, geometric non-linear effect and the influence of stay wire initial stress. The Dynamic Properties research about Guyed Transmission is conducted. It concluded that stay wire and tower's mode of vibrationare are relatively independent ,coordinated and the interaction of each other. Natural frequency of vibration and mode of vibration appears regularly and alternately changes with the increase of the formation order .Stay wire initial stress is main factor affecting the natural frequency of the structure and the frequency increases with the increase of stay wire initial stress.
