Reverse engineering technology in the process of automotive component innovation

Kender Štefan

Hutnik, Wiadomości Hutnicze

2023

Vol. 90, nr 3

16--23

The paper presents the possibilities of using reverse engineering technology in the digitization of automotive components and their innovation. The selected car component was digitized. A CAD model of the part was created based on the scanned point clouds. Point clouds were scanned by a laser 3D scanner in PolyWorks software. The reference 3D model was created from a point cloud in CATIA V5. It is then possible to compare the scanned point cloud and the reference model. The comparison of the scanned point cloud and the reference model is performed in PolyWorks. The process of scanning an automotive component using the FARO PLATINUM ARM 3D scanning arm is documented. The reference 3D model was subsequently modified and innovated for the facelift car model.

W artykule przedstawiono możliwości wykorzystania technologii inżynierii odwrotnej w digitalizacji podzespołów motoryzacyjnych oraz ich innowacyjności. Wybrany element samochodu został zdigitalizowany. Na podstawie zeskanowanych chmur punktów stworzono model CAD części. Chmury punktów skanowano laserowym skanerem 3D w programie PolyWorks. Referencyjny model 3D został stworzony z chmury punktów w programie CATIA V5. Możliwe jest wówczas porównanie zeskanowanej chmury punktów z modelem referencyjnym. Porównanie zeskanowanej chmury punktów z modelem referencyjnym odbywa się w programie PolyWorks. Udokumentowano proces skanowania komponentu samochodowego za pomocą ramienia skanującego FARO PLATINUM ARM 3D. Referencyjny model 3D został następnie zmodyfikowany i udoskonalony na potrzeby modelu samochodu po liftingu.

Unconventional Methods of Joining Composites and Metals in the Context of Weight Reduction of Car Bodies

One of the basic trends in the automotive industry today is to achieve the most acceptable ratio between the total weight of the car to its overall performance and utility properties. Reducing the weight of cars is largely due to the use of new materials, where composite materials offer a wide space for their application. Composite materials have their specific properties which is very beneficial in reducing the total weight. Another advantages is strength, stiffness, low fiber density, the ability to form them into any shape based on the required applications. One of the challenges associated with the use of composite materials is the search for new technological possibilities of joining composite materials with metals. These include technologies as for example riveting, ultrasonic welding, but especially gluing. Bonding is currently one of the most preferred ways of joining composite materials. The paper deals with testing of technology of bonding composite materials with metals used in the manufacture of automobiles and a comparison of individual results obtained from the experiment.
