摘　　要：本文提出了一种改进的二维Kimura 谱估计法,并应用于估计斜、正齿轮齿面周期误差的频谱结构以实现误差诊断和精度评价。二维功率谱较一维功率谱能更好的揭示齿面波形的空间特征和全面诊断加工系统的误差源。In this paper,a improved 2-D Kimura spectral estimation method is proposed and applied to estimating the freqency components of tooth surface periodic error of the cylindrical gear.Compared with 1-D power spectrum,2-D power spectrum of the gear toothsurface error is perfect fo show the space characterization of the tooth surfacewaviness and to diagnose the main periodic error sources in the machine-tool-workpiece system.
