摘　　要：以有限个梁单元模拟输电导线状态,采用最小位能原理推导出有限元方程,最后利用强制边界条件给出单元位移和应力方程,并运用仿真系统进行模态和谐响应分析。其结果可为以后线路优化设计提供依据。With the principle of minimum potential energy, a finite number of beam elements are used to simulate transmission lines to derive a finite element equation. Based on coercive boundary conditions, element displacement and stress equation are obtained. By using a simulation system, this essay mainly deals with modal analysis and harmonic responses analysis for optimal transmission line design.
