| 摘 要： | 以起重机轨道作为研究对象,研究了一种高精度、可自动化测量和实时在线分析的大长度轨道直线度的测量方法和装置。该方法利用准直激光束作为直线基准,携带光斑位置探测装置的小车行走于轨道上并根据激光光斑位置确定轨道测量点的偏差参数。光斑位置探测装置由一个接收屏、光路成像系统和一个二维PSD组成。针对300m长的起重机轨道的直线度测量,分析了装置的测量原理、数据处理方法,以及控制系统结构。并通过精度分析和误差评估证明了该方法和装置的可行性,仿真计算结果表明其原理误差仅为10-5mm数量级,完全符合大长度轨道的测量要求。 |

| Abstract: | A high precision method and an equipment of measuring the parameters of large-length crane rails, which could be automated measurement and real-time online analysis, is presented. This method uses collimated laser beams as datum lines; places a car carrying spot position detector walks on rail; then obtains parameters of the rail according to the spot position. The spot position detector mainly consists of a larger receiver screen, optical system and a twodimensional PSD. The measurement principle, the data... |
