摘　　要：本文以正弦振动为例,结合相应的国标指导,介绍了电工电子和(或)核仪器类产品进行型式试验过程中机械振动试验方法的研究,以考察产品能否经受住预定的振动条件,并根据经受试验不同严酷等级的能力来划分设备等级。Taking sinusoidal vibration as an example, this article summarizes the research on the method of vibration test in the process of type test for electric and electronic products or nuclear instrument products. This research is to investigate whether the products can go through the predetermined vibration requirements, and to further mark out equipment class according to the capacity of enduring different degree of severities during the test.

关 键 词：正弦振动 交越频率 动态特性 扫频耐久 定频耐久
