【Abstract】 Fretting wear of electrical connectors is one of the common failure modes of electrical connectors. In this paper, the self-organization model of fretting wear of electrical connectors is constructed based on cellular automata method. The value of cellular oxidation probability is accurately defined, and the cell volume of abrasive wear cutting is optimized. The relationship between empirical value and metal coating factor is drawn by comparing simulation data with experimental data. According to the coating factor and the effective resistivity of the coating, a new parameter is proposed to replace the original empirical value. The calculation of effective resistivity is avoided. The calculation formula of contact resistance is simplified, which provides a certain reference value for the design, selection and optimization analysis of electrical connectors.更多还原
