结合单柱地轨型三坐标机的结构特点，通过对横梁的分析进而对立柱进行了详尽的研究，这些研究包括对立柱的结构分析、受力分析和误差分析。最后指出由立柱弹性变形引起的测量误差可以和由其它因素引起的测量误差相迭加，并可进行软件修正。
Combined with the structural characteristics of single-column orbit-type CMM, the column is further studied through the analysis of the beam. These studies include the structural analysis, force analysis and error analysis of the column. Finally, it is pointed out that the measurement error caused by the elastic deformation of the column can be superposed with the measurement error caused by other factors, and the software can be corrected.
