摘要
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。
Based on the bending theory of beams,an analytical solution of end bending moment of transmission line under uniformly distributed wind load is obtained by means of technique of singular perturbation.A semi-experimental formula for engineering application is deduced out.The obtained results may serve as the theorctical basis for design of high-voltage transmission lines.
