| Abstract: |
| The work aims to form an engineering method to shorten the time of reliability evaluation and reduce the cost of test. On the basis of GJB 899A—2009, according to the actual characteristics of radar products, an appropriate timing statistical test program was selected to determine the reliability evaluation test profile. With reference to domestic and international acceleration test standards, Arrhenius model, Norris-Landzberg model and fatigue cumulative damage model were adopted to accelerate the temperature, temperature cycling and vibration stress level in the reliability evaluation test section to obtain the equivalent test profile and fault time. By calculating the equivalent profile of the reliability acceleration test, the radar reliability evaluation test time was equivalent to 367 hours under the acceleration condition from 1100 hours. The reliability acceleration test method of ground radar can obviously shorten the test time and reduce the test cost, and can be popularized and applied in engineering. |
