Abstract: The paper presents a design and analysis methods of carbon /epoxy composite tubular parts. Testing and analytical computations, based on classical laminated plate theory, of the proposed and manufactured material delivered the engineering constants that have been used in the finite element simulations of two important safety tests for the handlebar (bending and torsion). The experimental results obtained for lateral bending test (critical test) are in agreement with the finite element simulations.

Abstract: Checking the symmetry of a Formula One (F1) car nose requires the measurement and inspection of complex surfaces and raises a number of challenges both in terms of the equipment used and the measurement strategy. Verifying the symmetry allows the identification of the asymmetrical areas regarding the critical aerodynamic elements of F1 car nose. This paper presents three methods to check the symmetry of a F1 car nose and to determine the deviation using symmetry points (by points measuring) in plane using 2D scanned profiles and 3D laser scanned surfaces. In order to acquire the symmetry points, and to scan the profiles and the surfaces, a state of the art multi-sensor CMM (Coordinated Measuring Machine) has been used and the data has been processed in CATIA V5.

Abstract: The paper presents the entire process of designing and optimizing an injection mold for a polystyrene plastic anchor. The design process begins with a comprehensive market study of the polystyrene plastic anchors available on the Romanian market, and the results of this study are then used for the creation of a new model of anchor. After this first stage of design, the resulted model is optimized in terms of the injection process using the simulation software Autodesk Moldflow Adviser. After establishing the final form of the polystyrene plastic anchor, the mold is designed in Catia V5 using a series of standardized components. Manufacturing set-up is done in Catia V5 and Cimatron. In the end, the validation of the mold is performed using the injection machine Haitian Mars 2-2500.
