摘要
在大量试验和频谱分析的基础上，从功率谱、倒频谱和自相关函数的测量中确立了２７个理论诊断参数，用以诊断滚动轴承内、外圈和钢球表面的波纹度。
Based on a large number of experimental results and by frequency spectrum analysis, 27 theoretical parameters for the diagnosis on the surface waviness of the inner and outer races and balls of the roller bearings are obtained from the measurement of power spectra, reciprocal frequency spectra and autocorrelation functions.
