| 摘要: |
| 本文推导了考虑初始弛度的输电线的非线性振动偏微分方程，和采用迦辽金过程而得常微分方程。应用多尺度法和 L-P(Lindstedt-poincare) 法求得了受谐扰力和脉冲激励的输电线非线性振动响应的近似解。分析了初始弛度对响应的影响，得到了一些有益的结果。 |

| Abstract: |
| The partial differental equation of nonlinear vibration of a suspended power line for consideration of initial degree relaxation is derived and a ordinary differential equation is obtained by using the Galerkin procedure. The an be found the approximate solutíons of nonlinear vibration responses of a power line under the harmoníc borces and pulse excitations. The influence of initial degree relaxations on the responses is analysed with some useful results. |
