Design of Transmission Line System 's Full Aero -elastic Model and Analysis of its Dynamic Behavior

摘要

The model ’s aerodynamic shape,mass and stiffness distribution have been controlled strictly when the full aero-elastic model of transmission line system is manufactured and tested in wind tunnel. Insulator Strings and spacers have been designed and made according to the comparison principle of aerodynamic shape and mass. The boundary constraint of the system has simulated actually its dynamics character. The dimensionless mode and frequency of the model also consist with the performance of prototype system. So it ’s a full aero-elastic model of transmission line system, and its tested result is more dependable and is a true copy of prototype according to the dynamic characteristics ’s comparison. The proposed model and the design method are successful in the simulation of static and dynamic action when studying the coupling action of the transmission line system.
