Abstract

Point clusters of measured shapes achieved with the digital light-in-flight recording by holography method, is combined with CAD - Computer Aided Design software to obtain convertible formats for design and simulation software. The point cloud is constructed to a b-spline surface by least square fitting. The b-spline surface is converted into IGES- format in order to be readable for CAD and other software. A simple deformation experiment is made which demonstrates the advantages of combining holographic measurements with FEA- analyzes in order to adjust the constraints, the boundary conditions and loads in the simulation model to better fit experimental results.
