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

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)"

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GJB4.7-83"舰船电子设备环境试验振动试验"与美军标MIL-STD-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GJB4.7-83修订的必要性。

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, orelectrical anomaly has occurred） butthe selection of endurance frequencies with proper duration. On the basis of comparison and analysis between GJB4.7-83 ＂Environmental Test of Shipboard Electronic Equipment Vibvation Test＂ and MIL-STD- 167-1A ＂Mechanical Vibrations of Shipboard Equipment （Type Ienvironmental Vibration）＂, this paper put forward amending necessity of GJB4.7-83.
