船体复杂曲面钢板成型自动检测方法研究

In the researches of automatic plate forming for double-curved plate, the automatic forming inspection is an important technique. In this paper, a new method has been developed to inspect the transverse shape and the longitudinal shape of inspecting surface in comparison with those of formed surface. The longitudinal shape of plate surface has been inspected based on a shell plate development in consideration of the plastic deformation generated in the process of plate forming, while the transverse shape has been inspected by error analyses of cross-curvature radius. The method presented in this paper can not only be applied to the automatic forming inspection, but provide directions for the reworking of unformed plate.
