Abrégé
(EN)
A surface scanner for conducting non-destructive inspection of complex surface structures and configurations. The scanner includes two flexible tracks, each fitted with a motor driven tractor assembly. A rigid beam track spans the two flexible tracks. The rigid beam track is coupled to each flexible track tractor assembly by articulating joints that permit movement at the joints along at least three independent axes. The rigid beam supports a third motorized tractor. This third tractor supports a compliant thruster assembly that deploys gimbaled mechanical impedance, ultrasonic and eddy current inspection probes. The movement of the scanner is controlled by a scan control system that includes both hardware and software for controlling the movement of the scanner over the surface to be inspected. The software also includes a teach mode that permits an operator to preprogram the scan pattern for the surface to be inspected using a global coordinate system, referencing points on the surface and the data display using an identical coordinate system. The scanner also includes a data acquisition and analysis system that control scanner functions and operations.

对复杂表面和结构进行无损检查的表面扫描器。扫描器包括两个柔性轨道,每个柔性轨道安装有马达驱动的牵引组件。刚性梁轨道跨越两个柔性轨道。通过铰接接头将刚性梁轨道连接到每个柔性轨道牵引组件,该铰接接头允许在连接处沿着至少三个独立轴运动。刚性梁支撑着第三机动化的牵引器。这种第三牵引器支撑着顺向推进器组件,推进器组件使用万向接头固定机械阻抗型、超声型和涡流型检查探头。扫描控制系统控制着扫描器的运动,该扫描控制系统包括控制扫描器在要检查的表面上的运动的硬件和软件。软件还包括允许操作者应用整体坐标系对要检查表面的扫描模式进行编程的指导模式,在该模式中将在表面上的点和应用相同的坐标系显示的数据对应起来。扫描器还包括控制扫描器的功能和操作的数据采集和分析系统。
