Abstract

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.
