En liten glimt in i den beslutsstödsmiljö för produktutvecklande företag som utvecklas inom forskningsprojektet “model driven development and decision support” tillsammans med våra forskningspartners. Förmåga att redan i konceptfasen, innan man bygger produkterna, kunna förstå kostnad, värde samt miljöpotential mm över hela livscykeln skapar enorma möjligheter att prova olika scenarios och lösningar.

The decision theater, transforming data into knowledge in conceptual design

10:51AM Sep 06, 2018
No Comment

One success factor in engineering design is the ability to make effective and risk-managed decisions in a timely manner. Rarely is a single person sufficient to resolve today’s complex, connected issues. Rather, a group of stakeholders possessing required expert knowledge needs to be enrolled as these issues normally requires a wide variety of expert competences, […]

Data-driven modelling in the era of Industry 4.0: A case study of friction modelling in sheet metal forming simulations

12:58PM Aug 11, 2018
No Comment

ABSTRACT With growing demands on quality of produced parts, concepts like zero-defect manufacturing are gaining increasing importance. As one of the means to achieve this, industries strive to attain the ability to control product/process parameters through connected manufacturing technologies and model-based control systems that utilize process/machine data for predicting optimum system conditions without human intervention. […]

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 […]

Augment skills and knowledge of engineering students through design-build-test projects

The engineer of the 21st century is expected to possess a broad range of skills and abilities. Besides more traditional technical knowledge and engineering skills, interpersonal skills, critical thinking, creativity, and design makes its way into the curriculum of our engineering education. Our underlying pedagogical approach to teaching design is based on constructivism. Which basically […]

Model Driven Decision Arena: an aerospace study

ABSTRACT The concept of Decision Theatre (DT) is of great interest to leverage knowledge sharing in early stage design decision events. Yet, few contributions show how to configure a DT to support design space exploration and concept selection in cross-functional teams. This paper describes the development of a model-driven decision arena (MDDA) for aero-engine sub-system […]

Samverkande robotar utvecklade av samarbetande ingenjörsteam

Studenterna i årskurs två har under vårterminen jobbat med en mekatronisk utmaning där uppgiften var att konstruera, bygga och programmera en autonom robot. Årets utmaning i projektkursen MT1458 fokuserade på samarbete, roboten skulle lösa en given uppgift så bra som möjligt genom att samarbeta med en robot konstruerad av en annan grupp studenter. En viktig […]

A model-driven decision arena: Augmenting decision making in early design

8:08AM May 14, 2018
No Comment

ABSTRACT A wide variety of expert competencies, transcending traditional disciplines, are needed to foresee and evaluate the impact of decisions in the conceptual phase of engineering design. Where this previously was a trade-off regarding design and development of the pure physical artefact it is now a complex ambiguity game involving all disciplines touching a solution […]

Öppet Hus på BTH

Under lördagen hade BTH öppet hus för att intresserade skulle få inblick i vilka studiealternativ som finns samt hur utbildningen är upplagd, samverkan med näringsliv och vilka labb-resurser mm som finns. Makerspacet hade öppet under dagen för att besökare skulle få se och känna på tekniken som våra studenter har access till.

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 […]
