In the transmission lines,the safety operation of the tower-line system is very important,Therefore,the ANSYS analysis software can be used to establish and analysis the tower-line system of the transmission lines. In the process of analysis,the model of the beam-truss hybrid element-coupled is build,the ground gravity load,wind load and ice load can be calculated by theoretical calculation,and the tower-line system model and separated ground model are respectively analyzed for dynamic,and get the natural frequency of vibration with the tower-line system and the separated ground. Based on the result which is analyzed by the scholars,in order to verify the accuracy of the analysis in this paper. To make the calculated result contrast analysis by Ansys,and get the deformation of the maximum stress node displacement process about the both cases.
