Abstract
This invention discloses a method, apparatus, device, and medium for impedance analysis of a composite material electrical overlap model. The method includes: establishing a composite material simulation overlap model based on model construction parameters, including construction parameters for the composite material layers, the metal material layers, and the fasteners connecting the composite material layers and the metal material layers; determining the initial electrical parameter distribution of the simulation overlap model based on preset operating parameters, including current density or potential; determining impedance influencing factor adjustment information based on the initial electrical parameter distribution; and performing impedance analysis on the simulation overlap model based on the impedance influencing factor adjustment information. This technical solution enables the study of the impact of impedance influencing factors on overlap performance based on a simulation overlap model, shortening the overlap performance testing cycle, improving overlap performance testing efficiency, and reducing overlap performance testing costs.
