摘要
在传统发动机振动信号测试过程中,常常需要计算出的宽带信号的结果具有较高的频谱分辨率。本文针对发动机振动信号的特点,提出了一种分段算法来计算信号的有效值。该方法能在保证实时性的同时,提高信号的频谱分辨率。实验表明,此方法简单有效。
In the course of traditional test process of vibration signal of engine, it often demands the calculation result of wide band signal with high resolution. The paper introduces a new method called segmentation algorithm to analysis the vibration signal. It can satisfy the requirement of both realtime and high resolution. And the experiment shows its effectivity.
