摘　　要：将现代谱估计中的AR模型应用于包含广泛频率成分的典型的滚动轴承振动信号分析 ,采用Marple算法 ,FPE判阶准则 ,以样本长度的均方根作为定阶上界计算AR模型参数 ,求得AR谱。通过AR谱与经典谱的实际对比分析 ,验证了所建AR模型的正确性和对滚动轴承振动信号分析的适用性 。AR model was used to process the typical vibration signals of rolling bearings by means of Marple algorithm and FPE order selection criteria and the best order can be reached between 1～ N . AR frequency spectra based on the given AR model was compared with that of the classical one and the results show some obvious advantages.

关 键 词：AR模型 滚动轴承振动 功率谱估计 定阶准则
