| 目的 根据提高电连接器可靠性的要求，研究振动对航空电连接器的影响。方法 针对研究所的现有设备，开展电连接器的振动测试。根据厂家数据使用Solid works对某型号电连接器进行参数化建模，通过COMSOL模态分析获得接触件的固有频率，使用ANSYS Workbench对接触件进行瞬态动力学分析和谐响应分析。在不同的振动方向、振动频率和振幅下测试电连接器的接触电阻。然后，对电连接器执行对数扫频测试，以获得振动加速度对接触电阻的影响，仿真得到振幅对接触压力的影响。结果及结论 垂直振动电连接器比水平振动电连接器具有更高的接触电阻峰值。频率幅度越大，接触电阻越大。在敏感方向上，振动加速度量增大，接触电阻发生剧烈变化。 |

| This paper aims to improve the reliability of the electric connector and study the effect of vibration on aviation electric connector. According to the existing equipment design institute of electric connector vibration test, Solidworks data was used for a certain type electric connector parameterized modeling according to the manufacturer, then COMSOL was used to contact pieces of modal analysis to get contact with natural frequency, and then ANSYS Workbench was used to contact a transient dynamics analysis and harmonic response analysis. At different directions of vibration, vibration frequencies and amplitudes, the contact resistance of electrical connectors was test. Then, the electric connector perform logarithmic frequency sweep was tested. The influence of amplitude on contact pressure is simulated. The contact resistance of the vertical vibration electrical connector has a higher fluctuation peak value than that of the horizontal vibration electrical connector. In the sensitive direction, the vibration acceleration measure increases and the contact resistance changes dramatically. |
