| 目的 通过加速试验评估典型电子装备在综合环境应力条件下的剩余贮存寿命。方法 针对电子装备在贮存过程中受综合环境因素影响的特点，提出一种综合考虑温度-振动-电应力等环境条件的加速试验方法，以已经达到设计贮存寿命的某典型电子装备为试验对象，开展温度-振动-电应力综合加速寿命试验。结果 通过4个月左右的综合环境条件贮存加速试验，验证和评估了典型电子装备具备5年的剩余贮存寿命，取得了良好的试验效果。结论 综合环境条件加速试验充分考虑了装备寿命期经受的环境因素，能够准确模拟装备服役期间各种环境应力叠加效应以及不同任务阶段环境因素的累积效应。 |

| Objective To evaluate the residual storage life of typical electronic equipment under integrated environmental stresses through accelerated test. Methods In allusion to the integration of various environmental stresses that affects storage life of electric equipment, an accelerated test method considering the integrated stress of temperature-vibration-electric was proposed. Meanwhile, an accelerated life test under the proposed method was conducted with typical electric equipment which has already reached the design storage life as experiment subject. Results Through an accelerated storage test under integrated stresses of about 4 months, the typical electronic equipment's residual storage life of 5 years was verified and evaluated, and good experimental results were obtained. Conclusion The accelerated test under integrated stresses takes into full consideration of the environmental factors experienced by electric equipment during the storage process, and it can accurately simulate the cumulative effects of various environmental stresses during the service period and different mission stages. |
