Safety Study Of The Roof Of The Automobile Based On The Reverse Engineering

Based on the reverse engineering is presented in detail, the readers to have a certainunderstanding of the foundation, proposed the use of reverse method the automobile top coverphysical model is transformed into the CAD model, in the absence of any geometric data andmake drawings, to achieve the top economic, rapid safety detection results put forward solutions.Based on the reverse engineering of a deeper understanding, in detail the variousmeasurement method in reverse engineering under the premise of the advantages anddisadvantages of each detection, contrast method, combined with its own measurement accuracydesired characteristics, determine the use of ATOS laser scanner on three coordinatemeasurement needed components in measurement. The various modern for scattered point noisereduction and filtering method, in combination with its point cloud model, through the actualoperation, the different methods of contrast and effect, complete the point cloud noise reductionand filtration treatment. In the grid point cloud based on Bezier curves and surfaces, by contrast,B spline and NURBS curves and surfaces of the respective characteristics, select the NURBScurve theory as the basis of composition, final implementation under the Abaqus finite elementanalysis.The application of reverse engineering, we quickly completed the top model of the CADreconstruction, in the optic tectum of safety requirements under the premise, through finiteelement software verification model of safety。...
