架空导线振动周期的研究在输电线路的振动研究中有着重要的工程背景。然而，对于悬索的振动周期，特别是考虑弯曲变形能影响和不考虑弯曲变形能影响的悬索振动周期的比较分析，还没有得到深入的研究。本文推导了考虑弯曲变形能影响和不考虑弯曲变形能影响时悬索振动周期的数学表达式。悬置钢丝的弯曲变形能主要来自于振动过程中的惯性力和重力。随着垂度比和吊索长度的增加，弯曲变形能的影响变得更加显著。建立了一个简单的实验装置，用于测量悬丝的振动周期。考虑弯曲变形能的影响，实验数据与我们的表达式结果一致。这些悬线振荡周期的表达式不仅具有理论价值，而且可应用于输电线路的工程设计。
The study of the oscillation periods of suspended wires has an engineering background in the oscillation of electric transmission lines. However, the oscillation periods of suspended wires have not yet been thoroughly studied, especially in terms of comparative analysis of their oscillation periods with and without the effect of bending deformation energy. Herein, mathematical expressions for the oscillation periods of suspended wires with and without the effect of bending deformation energy are derived. The bending deformation energy of suspended wires results from the inertial and gravitational forces during oscillation. As the sag ratio and length of the suspended wire are increased, the effect of bending deformation energy becomes more significant. A simple experimental apparatus is set up to measure the oscillation periods of suspended wires. The experimental data are consistent with the results of our expression including the effect of bending deformation energy. These expressions for the oscillation periods of suspended wires not only have theoretical value but could also be applied in the engineering design of electric transmission lines.
