中文摘要:
      目的 缩短可靠性鉴定时间,降低试验费用,形成工程化方法。方法 以GJB 899A—2009为依据,根据雷达产品的实际特点,选择合适的定时统计试验方案,确定可靠性鉴定试验剖面。参考国内外加速试验标准,运用阿伦尼乌斯模型、Norris-Landzberg模型、疲劳累积损伤模型对可靠性鉴定试验剖面中温度、温度循环、振动应力水平进行加速,分别给出温度、温度循环、振动应力加速因子计算方法,得到加速条件下的等效试验剖面及故障时间。结果 通过可靠性加速试验等效剖面计算,雷达可靠性鉴定试验时间由1100 h等效为加速条件下367 h。结论 地面雷达可靠性加速试验方法能够明显缩短试验时间,降低试验成本,可以在工程中推广应用。
英文摘要:
      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.
