摘要/Abstract

摘要： 大直径钢筒在制作、运输、安装及运行时均可能因某些原因导致其出现一个或多个圆度异常区,以至于不满足设备验收和运行的相关要求。目前,针对大直径钢筒圆度异常的检测方法均较为复杂,并不适合快速检出。为此,本文基于三坐标测量原理,结合高精度全站仪的非接触自动测量模式,并采用Matlab编制了自动搜索程序,提出了大直径钢筒圆度异常区的快速检测方法。通过AutoCAD算例模拟和现场实测,结果表明,该检测方法不仅速度快,且可通过增加测点密度实现大幅提高检出精度,为后续修复和改进工作提供准确数据。

Abstract: Large diameter steel cylinders may have one or more roundness anomalies for some reason, during fabrication, transport, installation and operation, which don't not meet the relevant requirements for equipment acceptance and operation. At present, the detection methods for large diameter cylinders are complex and not suitable for rapid detection. In this paper, based on the principle of coordinate measurement, combined with the non-contact automatic measurement mode of high-precision total station, an automatic search procedure is prepared by Matlab program, and a rapid detection method of large diameter steel cylinder roundness anomaly area is proposed. The simulation by AutoCAD and the results of field measurements show that the inspection method is not only fast, but also can significantly improve the detection accuracy by increasing the density of measurement points, providing accurate data for subsequent repair and improvement work.

Key words: large diameter, steel cylinder, roundness, coordinate measurement, non-contact
