【摘要】 本文提出了建立主轴回转误差连续模型的Ｐｒｏｎｙ谱分析方法，并通过奇异值分解来确定误差信号中所含的谐波个数，为从根本上解决圆度与圆柱度误差分离技术中的“谐波抑制”问题奠定了基础。更多还原

【Abstract】 A Prony spectrum model construction for spindle revolving error is discussed in this paper. The method of singular value decomposition used to determine the number of harmonics is also proposed. All these works are to lay a foundation to thoroughly solve the problem of harmonics depression.更多还原
