摘　　要：激光跟踪仪在测量回转轴定位精度时,受到角度测量误差影响较大,须先进行误差分析以评估测量结果的可信度。以水平转台为例,对一种比较典型激光跟踪仪测量回转轴定位精度的方案进行误差分析,给出了不确定度的计算方法,为同类回转精度测试的测量误差分析提供实用参考。Considering the major error caused by angle measuring system while positioning accuracy of rotation axis is tested by laser tracker,it is necessary to analyze the uncertainty error before testing,which can verify the reliability of testing result.Taking the horizontal turntable as an example,the error of a typical scheme of laser tracker measuring the positioning accuracy of the rotation axis is analyzed,and the calculation method of the uncertainty is given,which provides a practical reference for the measurement error analysis of the same kind of rotation accuracy test.
