GJB4．7—83“舰船电子设备环境试验振动试验”和MIL—STD-167—1A“舰船设备的机械振动（Ⅰ类-环境振动）”的分析与对比

设备的振动试验不仅涉及到设备共振频率（或响应极值频率）和设备功能或结构完整性受影响的非响应极值频率（如任何出现结构、功能、机械或电气异常的频率）的确定，还有耐久试验频率及适当试验时间的选择。本文在对国军标GIB4．7-83誓舰船电子设备环境试验振动试验”与美军标MILSTD-167—1A“舰船设备的机械振动（Ⅰ类-环境振动）”比较和分析的基础上，提出了GJB47—83修订的必要性。

Analysis and Comparison between GJB4.7-83 "Environmental Test of Shipboard Electronic Equipment Vibration Test" and MIL-STD-167-1A "Mechanical Vibrations of Shipboard Equipment(Type Ienvironmental Vibration)"

Vibration test of equipment relates to not only the determination of resonance frequencies(or response prominence frequencies) and non-response prominence frequencies where functional or structural integrity is affected(any frequency at which a structural,functional,mechanical,or electrical anomaly has occurred) but the selection of endurance frequencies with proper duration. On the basis of comparison and analysis between GJB4.7-83"Environmental Test of Shipboard Electronic EquipmentVibration Test" and MIL...
