| 摘 要： | 提出了一种基于航天继电器微粒碰撞噪声检测(PIND)试验信号的多余物材料特征提起方法。以PIND试验输出的声音、加速度信号为研究对象,提出两种信号的预处理方法,并给出3种判断多余物特征的特征量定义方法。对实际继电器进行了PIND试验,验证了预处理方法和特征量的有效性。

| Abstract: | A feature extraction method of remnant material based on aerospace relay particle impact noise detection(PIND) experiment signal was presented.Taking sound and acceleration signals from PIND experiment output as research object,the preprocessing method of the two signals was presented,and three feature definition methods which judge remnant feature were given.The PIND experiment on actual relay was done,and validity of the preprocessing method and feature were proved. |
