dc.description.abstract | Denne artikkelen fokuserer på kalibrering av ekstruderte åpne aluminiumsprofiler for å forbedre dimensjonsnøyaktighet. Gapåpningstoleranser i ekstruderte profiler har vist seg å være utfordrende å kontrollere, og overgår ofte dimensjonskrav for påfølgende prosesser som automatisert sveising. Denne studien introduserer en ny kalibreringsmetode kalt Transversal Strekking and Lokal Bøying (TSLB). En rekke fysiske eksperimenter er utført for å undersøke egenskapene til kalibreringspros- essen, mens numeriske simuleringer i Abaqus er brukt for å få en bedre forståelse av prosessatferden. Den presenterte metallformingsmetoden har vist en betydelig forbedring, og reduserer dimensjonstoleransene til ekstruderte U-kanalprofiler med en faktor på 10, vel innenfor kravene til automatisert sveising. | |
dc.description.abstract | This research paper focuses on the calibration of extruded open aluminum profiles to enhance their dimensional accuracy. Gap opening tolerances in extruded pro- files have proven challenging to control, often surpassing the dimensional require- ments for subsequent processes like automated welding. This study introduces a novel forming-based mechanical calibration method called Transverse Stretch- ing and Local Bending (TSLB) to improve the dimensional accuracy. A series of physical experiments were conducted to investigate the capabilities of the calibra- tion process, while numerical simulations using Abaqus were employed to gain a better understanding of the process behavior. The presented calibration method has demonstrated a significant improvement, reducing the dimensional tolerances of extruded U-channel profiles by a factor of 10, satisfying the requirements for automated welding. | |
