Measurement error analysis and modeling methodfor complex curved surface of part shell

The invention provides a measurement error analysis and modeling method for a complex curved surface of a part shell. The method comprises the following steps: carrying out error analysis and modelingwhen projections of two measuring heads on an XY plane are not overlapped, and carrying out error analysis and modeling when vertex angle measurement deviation is caused by eccentricity of a modelingworkpiece and a rotary table. 本发明提供零件壳体复杂曲面测量误差分析与建模方法，包括下列内容：两个测头在XY平面投影不重合时的误差分析与建模工件与转台偏心引起顶角测量偏差时的误差分析与建模。
