Research Institution
The objective of the proposed research is to develop an integrated system for dynamic stress analysis of aircraft tires. The system will use the Projection-Moire concept, whereby a high-density line-set of Master Grating is projected on the investigated surface. The projected lines, deformed by the displacements and bending of the investigated surface is then optically recombined with a reference set, producing the Moire Fringe pattern. As operational system will be assembled and testing will be conducted to prove the feasibility of the proposed approach. The designed system will include a projection master and a PC-controlled CCD camera to receive the image, and produce the Moire fringes, using software generated reference grating. Software will be developed to analyze the fringe pattern, retrieving the displacement and stress information.
