摘要:

以矢谱分析为基础,提出了一种针对双通道振动信号的分析方法--矢功率谱分析.从矢谱基础理论出发,证实了转子同一截面上互相垂直的任意两个通道在各频率响应下的能量总和为一定值这一结论,并以此为前提给出矢功率谱分析的表示方法,然后利用参数模型功率谱估计中的AR模型实现了双通道数据集成的AR功率谱估计;因计算过程较为繁琐,提出简化算法,对两个信号的处理可以同步进行,最后用C++Builder 5.0编程实现了这一分析方法,并用实际数据验证了其实用性.

Abstract:

Based on vector spectrum analysis, an analysis method for two-channel vibration signals - vector power spectrum analysis is proposed. Starting from the basic theory of vector spectrum, the conclusion that the sum of the energy of any two channels perpendicular to each other on the same section of the rotor under each frequency response is a certain value, and the representation method of vector power spectrum analysis is given on this premise, and then the AR model in the power spectrum estimation of the parametric model is used to realize the AR power spectrum estimation of dual-channel data integration. Due to the cumbersome calculation process, a simplified algorithm is proposed, and the processing of the two signals can be synchronized with each other, and finally this analysis method is realized by C++Builder 5.0 programming, and its practicality is verified with actual data.
