The Influence of Base Pre-Tilting on the Dynamic Properties of Angle Towers
As a significant bearing tower that is widely adopted in the electric transmission line, the angle tower is frequently found over-tilting in the inspection and maintenance of transmission lines. On the basis of the massive universal finite element software ANSYS, this study establishes a three-dimensional steel frame for the commonly used 500kV angle tower in the Inner Mongolian area, and analyzes the dynamic properties of angle towers while setting the base pre-tilting. It also conducts model analyses for the towers with or without base pre-tilting respectively, compares the frequency and mode of vibration, and paves way for further study of the setting of base pre-tilting and vibration response analysis.
