Optimization of reliability evaluation method based on fault correction test

The occurrence of product failure during the aviation equipment test directly affects the reliability level. Whether the failure is corrected and the correction strength will also directly affect the reliability evaluation method and results. The situation encountered in the equipment test stage is complex and diverse, which poses a great challenge to reliability evaluation. In this paper, aiming at the problems of limited reliability growth assessment and difficult engineering application caused by the diversity of fault correction timing in the process of field test, the methods of non-correction test, immediate correction test, early correction test, delayed correction test, partial immediate correction test, single equipment complex correction test a nd multi-equipment complex correction test are studied step by step. The corresponding reliability evaluation model is put forward and applied to engineering practice, which improves the accuracy of equipment reliability evaluation results in fligh t test stage.
