Abstract
The dynamic behavior of two-span suspended transmission lines is studied. The equations of the two-span transmission lines are obtained with the help of Hamilton’s principle. Meanwhile, the boundary and continuity conditions are ensured by the mechanics equilibrium condition. Then setting the determinant of the coefficient matrix equal to zero, the exact eigenvalues can be given. Then, the results of the parametric analysis of the in-plane and out-of-plane eigenproblems are presented, and the frequency avoidance phenomena are introduced. Finally, the possible nonlinear interaction of two-span transmission lines is examined.
