Abstract

Considering bending stiffness,an finite element model is proposed to overhead transmission based on Euler beam.In this model,the displacement of the unit beam is represented by assumed mode method,and derived the mass matrix and stiffness matrixof unit beam by using assumed mode method,secondly,deduced Lagrange equation using d'Alembert principle and vibration differential equation of unit beam.And then the concept of global coordinates is proposed,which is used to represent the entire transmission line system composed of several unit beam.Taking the LGJ-400/95 as the research object,the inherent characteristics of natural frequencies and mode shapes of the transmission lines and the vibration response under the loads of the different forms can be obtained by using the finite element model to analysis the vibration characteristics of the overhead transmission lines.
