本文应用梁的弯曲理论 ,对空间均匀分布风载激励的输电线振动 ,采用奇异摄动方法给出了端部弯矩的解析结果 ,并以此为基础 ,给出了适合于工程设计的半经验公式 ,所得结果为提高高压输电线的安全设计提供了理论分析基础。
In this paper, the bending theory of beam is used to analyze the vibration of the power line with uniform wind load distribution. The analytical results of the bending moment of the end are given by the singular perturbation method. Based on this, The empirical formula and the results provide the theoretical basis for improving the safety design of HV transmission lines.
