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.
