摘　　要：针对采用弯曲成型工艺制造的核电波动管尺寸检测困难的问题,基于三维扫描技术提出了一种适用于波动管弯曲角度测量的方法,研究了采样区位置及采样截面数量对测量结果的影响,并验证了测量结果的重复性和准确性,研究结果表明:当起始距为200 mm,截面数目为5时,测量效果最佳;多次测量结果的最大重复性误差为0.0192%,重复性精度良好,与三坐标测量仪对比结果偏差范围小于0.05°,测量精度高。In order to solve the problem of difficulty in detecting the size of the surge pipeline for nuclear power station manufactured by bending process,a method applicable for the measurement of the bending angle of the surge pipeline was proposed based on the three-dimensional scanning technology.The influence of the location of sampling area and the number of sampling cross-sections on the measurement results was studied.The repeatability and accuracy of the measurement results were verified.The research results show that the measurement effect is the best when the initial distance is 200mm and the number of cross-sections is 5.The maximum repeatability error of multiple measurement results is 0.0192%,the accuracy of repeated measurement is good,and the deviation range of the results compared with the three-coordinate measuring system is less than 0.05°,with high accuracy of measurement.
