| 目的 深入研究应力间的耦合作用，为多应力试验提供理论支撑。方法 以J599Ⅲ型电连接器为研究对象，依托现有设备设计典型航空电连接器热电耦合试验，并分析试验结果。使用SOLIDWORKS对电连接器进行建模，然后使用COMSOL Multiphysics进行热电耦合的有限元分析，与试验结果进行对比。结果 电流为1 A时，接触件表面温度最大值位于插针与插孔的接触区域，最大温度为24.4 ℃，温升为0.1 ℃，插针接触区域中心部位温度最高，达到26.7 ℃。当电流为8 A时，可以产生约6 ℃的温升。仿真得到的温升值要略高于试验值。接触电阻随温度的升高而增大。结论 温度和电负载都会造成电连接器接触部位的温升和接触电阻的升高。 |

| In order to provide theoretical support for multi stress test, the coupling effect between stresses is studied deeply. Based on the existing equipment, the typical thermal coupling test of J599 Ⅲ electrical connector is designed and the test results are analyzed. SOLIDWORKS is used to model the electrical connector, then COMSOL multiphysics is used to analyze the thermoelectric coupling, and the results are compared with the experimental results. When the current is 1 A, the maximum temperature of the contact surface is located in the contact area between the pin and the socket. The maximum temperature is 24.4 ℃, the temperature rise is 0.1 ℃, and the temperature at the center of the contact area of the pin is the highest, reaching 26.7 ℃. When the current is 8 A, a temperature rise of about 6 ℃ can be produced. The simulated temperature rise is slightly higher than the experimental value. The contact resistance increases with the increase of temperature. Temperature and load will cause the temperature rise and contact resistance of the contact part of the electrical connector. |
