ABSTRACT:
A panel testing device includes a frame, a first roller assembly pivotally mounted to the frame including a first roller and a second roller spaced apart from and substantially parallel to the first roller. The panel testing device also includes a second roller assembly pivotally mounted to the frame having a third roller and a fourth roller spaced apart from and substantially parallel to the third roller. The device is configured such that the first and third rollers may be engaged with a first side of a test panel and the second and fourth rollers may be engaged with a second side of the test panel. The first and second roller assemblies are pivoted in opposing directions to bend the panel. A LASER displacement sensor is mounted on a movable manipulator measures the deflection of the panel as the panel is bent.
