摘要：电连接器的接触电阻是衡量电连接器接触性能的重要指标，为研究电连接器在温度场、电流场与振动场同时作用下接触电阻变化规律，基于多物理场耦合下接触电阻理论，采用 ANSYS 与 COMSOL 软件进行仿真，以 REB 型电连接器为实验对象，通过正交实验对仿真结果进行分析，验证了接触电阻理论的正确性并得到了各物理场对接触电阻的影响规律。

Abstract: The contact resistance of electrical connectors is an important indicator to measure its contact performance. In order to make research on the contact resistance variation of electrical connectors under the simultaneous actions of temperature field, current field and vibrating field, the paper, based on the contact resistance theory under the multi-field coupling, adopts ANSYS and COMSOL for simulation analysis. Then, taking the REB electrical connector as the experimental object, the paper makes analysis of simulation results through the orthogonal experiment. It not only verifies the correctness of the contact resistance theory, but also achieves the law of physical fields’ effects on the contact resistance.

Key words: electrical connector; multi-field coupling; orthogonal experiment; contact resistance
