| Abstract: |
| Objective To improve the reliability level of a rocket electrical equipment by a reliability enhancement test. Methods The development status of reliability enhancement test technology at home and abroad was analyzed, and the design criteria of test conditions and the design of test section were expounded. Results The reliability enhancement test of the rocket electrical equipment revealed faults of a large number of products. The reliability level of the product was improved through improvement of the design. Conclusions The reliability enhancement test can improve the reliability level of products rapidly. Corresponding suggestions on implementation of follow-up test are proposed according to some issues existing in the testing process. |
