| 摘 要： | 分析了振动试验中功率谱密度曲线出现低频上翘现象的原因，并用Matlab仿真方法进行分析验证，证实了信号中极低频成分或高量级低频脉冲信号成分与分析方法的联合作用是导致出现低频上翘现象的原因。提出了振动试验中低频上翘情况的处理方法和应对措施。

| Abstract: | The reason of PSD curve turning up at low frequency in a random vibration test was analyzed.It was validated by simulating in Matlab that the combination of super-low frequency signal or the high level pulse and specific analyzing method are the causes.Some methods and measures to handling the problem were put forward. |
