为解决特高压输电线电力金具U型挂环易破坏的问题.利用有限元软件
根据实际线路设计参数
建立U型环的有限元模型
对结构进行静动态分析.计算结果表明:在静态分析中
U型挂环的最大应力位置为中心接触部位
其最大等效应力为1 482 MPa
上下U型挂环之间出现滑移
滑移距离为0.8 um;动态分析中
U型挂环在第六阶变形最为严重
并且在水平载荷和垂直载荷的共同作用下
位移振幅最大处的频率为2 700 Hz
振幅值为1.304 6×10-4 mm
应力值为33.481 MPa
此时频率接近于结构固有频率
结构易发生共振现象.研究结果为进一步研究输电线路电力金具的动力学分析提供理论参考.
In order to solve the problem that the U-shaped ring of UHV transmission line is easy to be destroyed
using the finite element software
the finite element model of U-ring is established
and the static and dynamic analysis of the structure is carried out according to the actual circuit design parameters.The calculation results show that in the static analysis
the maximum stress position of the U-shaped loop is the central contact part
and the maximum equivalent stress is 1482 MPa.The slip between the upper and lower U-shaped loops is 0.8 um.In the dynamic analysis
the U-shaped loop is the most severely deformed in the sixth order
and under the combined action of the horizontal load and the vertical load
the frequency at which the displacement amplitude is maximum is 2 700 Hz
the amplitude value is 1.304 6×10-4 mm
and the stress value is 33.481 MPa
at this time
the frequency is close to the natural frequency of the structure
and the structure is prone to resonance.The research results provide a theoretical reference for further study of the dynamic analysis of power lines for transmission lines.
