采用电蚀法模拟了滚动轴承的典型故碍疲劳点蚀在振动试验台上对百余套轴承进行了试验分析,由用振动信号测试处理系统实测了不同状态下轴承的时序波形及频谱图。在此基础上提取8个特征参数,用灰色关联分析法对受试轴承进行了分类识别,结果与实际吻合。 The typical eroded pitting corrosion of the rolling bearing was simulated by the electric erosion method. A hundred sets of bearings were tested and analyzed on the vibration test rig. The timing waveform and spectrogram of the bearing under different conditions were measured by the vibration signal test and processing system. Based on this, eight characteristic parameters were extracted and classified by the gray relational analysis method. The results were in good agreement with the actual results.
