Abstract
The vibration of a single-conductor transmission line with a Stockbridge damper is examined by modeling the system as a double-beam concept. The equations of motion are derived using Hamilton’s principle, and expressions are presented for the frequency equation, mode shapes, and orthogonality conditions. The analytical results are validated experimentally. The effect of the damper characteristics and location on the system natural frequencies is investigated via a parametric study. The role of the latter with respect to frequency is inconclusive. The present approach enables transmission lines designers to determine the exact natural frequencies and mode shapes that are required in the study of the vibrational response of a single conductor with a Stockbridge damper.
