摘要

由多面体和自准直仪组成的编码器角度检测系统测量编码器误差

得到的编码器误差中不但包含编码器误差

而且包含多面体检定误差.根据两步法的使用条件

将两步法应用于光电轴角编码器测角误差数据的处理

分别得到多面体检定误差和编码器测角误差

误差分离的结果与采用其他方法得到的结果相近

但用两步法计算需要的测量数据大大减少.比较结果证明

与其他测量方法相比

此方法可以提高测量效率90%以上

缩短检测时间近80%.

Abstract

The encoder errors obtained by measuring the encoder errors with an encoder angular testing system consisting of polyhedrons and an autocollimator

include encoder errors and calibration errors of polyhedrons. According to the conditions for use of two-step method

the two-step method is applied to the processing of photoelectric rotary encoder errors

and the calibration errors of polyhedrons and the encoder errors are separately obtained. The results of error separation are close to the results obtained by other methods

but the volume of data to be measured for use of two-step method is dramatically reduced. The results of comparison show that

in comparison with other methods

this method can be used to improve the measurement efficiency by more than 90%

and shorten the measurement time by nearly 80%.
