VIPP – Volvo Industrial PhD Programme

At Volvo Cars annual VIPP meeting, BTH’s PhD student Johan Pilthammar presented his research findings and received very good comments from the management team. His supervisor Prof. Sharon Kao- Walter was also invited and got a very good impression of the Volvo survey. About 30 industrial projects are in progress and more than 10 new […]

Introductory study of sheet metal forming simulations to evaluate process robustness

ABSTRACT The ability to control quality of a part is gaining increased importance with desires to achieve zero-defect manufacturing. Two significant factors affecting process robustness in production of deep drawn automotive parts are variations in material properties of the blanks and the tribology conditions of the process. It is imperative to understand how these factors […]

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 […]

Elastic Press and Die Deformations in Sheet Metal Forming Simulations

ABSTRACT Never before has the car industry been as challenging, interesting, and demanding as it is today. New and advanced techniques are being continuously introduced, which has led to increasing competition in an almost ever-expanding car market. As the pace and complexity heightens in the car market, manufacturing processes must advance at an equal speed. […]

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 […]
