Verification of Numerical Simulation Using a 3D Optical System for Measuring Deformations
Zakl, Alexandr ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This master’s thesis discusses the current state of optical metrology and its place in manufacturing and optimization of parts made by deep-drawing technologies. First part is devoted to building a solid knowledge base in different fields that this thesis draws from. These fields are Optical Metrology, deep drawing of sheet metal and simulations using finite elements method. Subsequently, in the experimental part there are chapters dedicated to Measurement and creation of material models and measurement of grid markings on deep-drawn parts provided by ACO Industries, measured by photogrammetric system from German Company GOM metrology. Additionally, for reference to the measurement, FEM software called PAM-Stamp is used to simulate and predict the final state of the parts after manufacturing. Furthermore, optical metrology was used during creation of material models, data supplied by this analysis was used as an input for the simulations. The last chapter then deals with the evaluation and comparison of measured and simulated data and drawing conclusions about the reliability of optical systems and modern technologies in technical practice.

The deformation necks and their use in engineering practice
Hovad, Jan ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This theses presents methods for aplication of the deformation necks. There are described advantages, disadvantages and recommendations for use in engineering practice for each method. Methods are compared with each other. There are also discussed manual and automatic methods of the measurement, including descriptions, advantages, disadvantages and comparation.
