| Abstract: |
| 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. |
