Abstract


Circular electrical connectors to Y11X-2221 as the object of study, analysis of the failure mechanisms of the electrical connector under the vibration stress , electrical connectors in the vibration of a statistical analysis of reliability test and the test data were studied . First, the development history and current status of the reliability research at home and abroad ; reliability test methods and trends , the reliability of statistical analysis methods and problems , as well as aerospace electrical connectors Reliability of the status quo and problems review and Comment . Secondly, through the scene, laboratory electrical connector failure statistics and analysis, that the electrical contact failure is the failure of the main form of electrical connector . Under normal operating conditions , causing the electrical connector in electrical contact failure , i.e. to decide the main reason of the working life of the electrical connector is the contact pressure is reduced , the fretting wear and the surface of the film growth , and the impact contact pressure , fretting wear the principal factors and changes in the surface layer vibration and temperature environment . Third, the structure of the electrical connector and electrical connector in the analysis of the dynamic characteristics of vibration stress of the failure mechanisms of the electrical connectors under the vibration stress , and came to the electrical connector in the vibration stress to failure at the physical equations . Further integration of the theory of probability and statistics , the electrical connector vibration stress the reliability of the statistical model , inverse power-law - Weibull model , laid the foundation for the the electrical connector reliability test program development and the statistical analysis of the test data . Fourth, through the electrical connector vibration stress accelerated life test , and the test data statistical analysis to verify the correctness of the reliability of the statistical model of the electrical connector . Estimated value of the initial value of the least squares and test data , the application of the maximum likelihood estimation method for statistical processing of experimental data , obtained electrical connector reliability of the estimated value of the eigenvalues ??. Finally, the full text of research are summarized, and pointed out the direction of reliability testing and analysis of the electrical connector study , further research is needed and the next step of the fund subject .
