本文揭示了谐波分析与圆度评价中误区的存在性以及误区中参数估计与谐波分量提取的结果失真性,这种误区可以表征为数学模型的近似、非线性舍去误差、人为偏心与一次谐波的混合、评价准则与标准公差定义的最小条件准则的差异。本文还给出了对误区的相应消除对策,即最大模范数最小法及其计算机辅助分析系统。
This paper reveals the existence of erroneous zones in harmonic analysis and roundness evaluation, as well as the result distortion of parameter estimation and harmonic component extraction in erroneous zones. This erroneous zone can be characterized as the approximation of mathematical models, the nonlinear elimination error, the artificial eccentricity and The first harmonics are mixed, and the difference between the evaluation criteria and the minimum criteria defined by the standard tolerances. This article also gives the corresponding elimination of misunderstandings, that is, the maximum model of the minimum method and its computer-aided analysis system.
