Study on Vibration Response Characteristics of Microtransmission Line
Overhead transmission wire under the condition of complex micro terrain wind vibration response research,often using the flow field and solid separate unidirectional coupling calculation,in this paper for this deficiency,based on the theory of bidirectional solid coupling theory,build micro landform under the transmission line wind environment vibration strong bidirectional coupling calculation method,and study the wind speed drop variable line vibration characteristics,found that the wind speed drop line periodic swing decay,and the swing amplitude related to drop gradient,but the period is basically unchanged.
