Abstract

The invention discloses a finite element simulation analysis method of a power wire clip. The finite element simulation analysis method comprises the following steps of S1, establishing a power wire clip model by three-dimensional software; S2, guiding the power wire clip model obtained in S1 into finite element simulation analysis software; S3, establishing a coordinate system, dividing meshes of the power wire clip model, and forming tetrahedral meshes; S4, applying the boundary conditions of the power wire clip model to simulate and calculate; S5, calculating to obtain results; S6, processing the simulation and calculation results into a simulation cloud atlas or an applicable data format, observing the whole and local states of stress distribution via the simulation cloud atlas, and determining the stress number of each part of the power wire clip on the simulation cloud atlas. The finite element simulation analysis method has the advantages that the wire clip can be quickly modeled, the stress of the wire clip is performed with simulation analysis, the stress centralizing part is obtained, and the key optimizing and defect monitoring on the stress centralizing part can be performed.

Description

technical field [0001] The invention relates to the technical field of wire clamps, in particular to a finite element simulation analysis method for power wire clamps. Background technique [0002] Power line clamps include suspension line clamps and strain line clamps. Suspension clamps are used for connecting wires, etc. on straight poles and towers; tension clamps are used to fix the ends of wires to bear the tension of wires, and hang the wires to the tension strings or fittings on towers. [0003] Suspension clamps are widely used in China now. They are an important fitting in overhead transmission lines. They are in direct contact with conductors in overhead transmission lines and play the role of stabilizing, supporting and suspending transmission lines. In actual working conditions, the suspension clamp is subjected to lateral, longitudinal and vertical forces, and the force state is more complicated, and the force of the suspension clamp determines the stress distr...
