摘要
基于研制的身管内膛检测机器人,对其激光位移传感器及PSD二维位置传感器在内膛检测装置中的相对安装位置误差进行了深入研究.提出了基于精密三维移动台及精密转台的标定测量方法,分析了身管内膛测量装置的工作原理及控制方法,并且对PSD与激光位移传感器之间的轴偏角及轴偏距进行了精确标定,阐述了具体的标定方法及步骤.通过对标定测量数据统计分析,确定了测量器件的关键位置参数.经160 mm标准管道的实验对比分析,表明该标定方法能够消除测量器件安装位置误差,保证了整个系统的检测精度,提高了测量结果的准确性.
Abstract
On the basis of the developed cannon bore detection robot,the relative installation position errors of its laser displacement sensor and PSD two-dimensional position sensor in the bore detection device are deeply studied.A calibration measurement method based on precision three-dimensional mobile platform and precision turntable is proposed.The working principle and control method of the cannon bore measuring device are analyzed,and the axis deflection angle and axis offset between PSD and laser displacement sensor are accurately calibrated,and the specific calibration methods and steps are described.Through the statistical analysis of the calibration measurement data,the key position parameters of the measuring device are determined.The experimental comparison and analysis of the 160mm standard pipeline shows that the calibration method can eliminate the installation position error of the measuring device,ensure the detection accuracy of the whole system,and improve the accuracy of the measurement results.
