摘要
依据双谱分析的基本原理、算法及其在工程中的理解,通过实验室实验中所得到的碰摩信号数据进行了双谱分析,实验表明,双谱分析能有效地识别故障特征、抑制噪声。
Based on bispectrum analysis basic principle, algorithm and in project understanding, the vibration signal empiricaldatum which acquired in the laboratory carries on the bispectnma analysis in view of the actual device, the experiment had indicated that the bispectrum analysis could distinguish the breakdown characteristic and denoise effectively.
