| 摘 要： | 提出了3种检测危险频率的方法。正弦扫频法以正弦扫频试验为基础,测量设备的响应曲线以识别危险频率;随机法基于频响函数随机测试原理,并利用FFT谱分析与随机信号处理技术,可根据情况分别采用幅频特性检测法、分量检测法、矢量检测法;脉冲法(锤击)的原理是利用锤头与设备敲击时产生的瞬态脉冲,从而激发出设备在一定频带内的危险频率。还从使用角度提出了一些建议。

| Abstract: | Three measurements for the dangerous frequency of the electronic equipments were put forward.The sine sweep method that make use of the sine sweep test measure the responds curve of the equipment and identify the dangerous frequency;the random method that use the technique of the FFT spectrum analysis and the random signal processing take the principle of the frequency responds function tests as foundation,it includes three methods;the principle of the pulse method(hammer shot) is,when the hammer shot the equipment,the pulse can excite the dangerous frequency within a given range.Some countermeasures were put forward. |
