Applied simulation and internet of things for reduced waste during sheet metal forming

Together with Volvo Cars (Olofström), Telenor Connexion and Blue Science Part as coordinator, a research and application project has been carried out within the “Test arena Blekinge” with the aim of transforming theory into practically applicable knowledge in Industry 4.0. Industrial digitalisation has been going on since the 1990s, and with the development of the […]

Samverkan “in real life” mellan BTH och medlemsföretag i Techtank

I mitten av mars besökte lärare och forskare från BTH, Blekinge Tekniska Högskola, två av Techtanks medlemsföretag i Olofström – EBP och Wugang Tailored Blanks. Syftet med besöken var bland annat att fördjupa kontakterna mellan högskolan och näringslivet genom att öka kompetensen om varandra och hitta samarbetsmöjligheter såsom exjobb och studentprojekt. Både företagen och högskolan […]

Experiments and FE-simulations of stretch flanging of DP-steels with different shear cut edge quality

ABSTRACT Dual-Phase (DP) steels are today used in the automotive industry due to its large strength to weight ratio. However, the high strength of DP-steel does have a negative impact on the general formability in sheet metal forming. Unfavourable process conditions in the press shop will, on top of this, reduce the formability of DP-steels […]

Framework for Simulation-Driven Design of Stamping Dies Considering Elastic Die and Press Deformations

ABSTRACT Sheet metal forming (SMF) simulations are used extensively throughout the development phase of industrial stamping dies. In these SMF simulations, the die and press are normally considered as rigid. Previous research has however shown that elastic deformation in these parts has a significant negative impact on process performance. This paper demonstrates methods for counteracting […]

Simulation-Driven Design Approach for Design and Optimization of Blankholder

 ABSTRACT Reliable design of stamping dies is desired for efficient and safe production. The design of stamping dies are today mostly based on casting feasibility, although it can also be based on criteria for fatigue, stiffness, safety, economy. Current work presents an approach that is built on Simulation Driven Design, enabling Design Optimization to address […]
