Analyzing some research results comparatively, the line’s mass and its tensile stiffness have influence on the tower’s dynamic character admittedly, but some conclusions have differences based on their actual projects. So 32 tower-line coupling models are designed under comparable conditions. Contrasting the mode parameters of each coupling model by ANSYS modal analysis, some significative conclusions have be gotten. The in-plan natural frequency of the coupling system is less than that of the single tower, and the line’s sag has a main influence on the frequency’s increment, contrarily the line’s span has an important effect on its decrease. The out-plane natural frequency of the coupling system with the same span is up-and-down markedly when its sag has be different, but few change when its span has be large. The torsional natural frequency of the coupling system is less than the single tower, and its trendline is complicated when the line’s sag has be different, but fall to the in-plane natural frequency when its span has be large gradually.
