机载电子设备耐振试验时间的确定与合格判据

Determination of vibration endurance test time and qualification criterion for airborne electronic equipment

根据新研飞机研制过程中提出的问题 ,论证了机载电子设备仍需进行耐振环境试验的必要性 ,提出了机载电子设备耐振试验时间的确定方法 ,并对耐振试验的合格判据进行了研究 ,结果表明耐振试验中 ,如机载设备仅发生由“一次通过破坏”或“峰值破坏”引起的功能故障 ,仍应判为合格通过。

Based on the problems met in the development of new aircraft projects, this paper describes the necessity of vibration endurance test for airborne electronic equipments, and put forward the determination method for the vibration endurance test time. The qualification criterion of the vibration endurance test is also studied in this paper. The result shows that during the vibration test, if the malfunction of airborne electronic equipment is caused by 'one try destroy' or 'peak value destroy', the equipment should be qualified to pass the vibration endurance test.
