| 摘 要： | 考虑几何非线性的影响,推导了两档输电导线与悬垂绝缘子串耦合振动的非线性动力学方程,并运用数值分析软件对不同工况下的振动响应进行了数值求解.基于输电导线振动的位移时程曲线,得到了两档输电导线的非线性耦合振动特性和共振特性,在小传输角度情况下,角度对输电导线的振动幅度没有明显影响,但振动系统的静平衡位置会发生偏移.

| Abstract: | The nonlinear vibration equations of two spans transmission line coupled with suspension insulator string were derived, where the geometric nonlinearity of transmission line was considered. Solutions under different working conditions were obtained by numerical analysis. The displacement time curves illustrated the characteristics of nonlinear coupled vibration and internal resonance of the system. In the case of small transmission angle, the value of the angle had no obvious effect on the amplitude of transmission line, but the static equilibrium position of system was offset. |
