Background and activities
About Terje RølvågBackground.
Rølvåg holds a MSc. and a Ph.D. within finite element dynamics of elastic mechanisms from NTH. His working experience includes Sintef Production Engineering, Sintef Materials Technology, Fedem Technology AS and TRAC, the latter in combination with an adjunct professorship at Department of Engineering Design and Materials (IPM), NTNU. Since 2003 he has been a full time professor within the Engineering Design group at IPM.
Rølvågs research interests cover computer science applied for engineering applications focusing on simulation of behaviour and strength of electromechanical products. The simulation techniques are based on non-linear Finite Element formulations and control science (FEDEM).
His research fields also includes Lean Product Development, focusing on the process of generating and generalizing knowledge that can be used (and reused) by product developers to create attractive products with maximum customer value. The relationship between design, function and manufacturability are important issues in lean product development.
Rølvåg is currently in charge of the PLM Lab and the LPD project. In this project, research scientists from Norway, Sweden and USA were developing new methods and tools for knowledge based product development ( we call it Lean Product Development ).
Entrepreneurship – Innovation.
Rølvåg has been central in developing FEDEM, a finite element based modeling and simulation tool with multidisciplinary capabilities (see www.fedem.com). The company was recently acquired by SAP, and Rølvåg is engaged by Fedem to adopt the software to Digital Twins. Rølvåg has also invented several new products like Easy Roller II, and has recently patented a generic flexible mechanism. In 2009-2011, Rølvåg implemetented this mechanism in ColiCot, a cradle for infants with colic or other sleeping problems. Rølvåg is currently working with Fedem development, new patents and innovative video based teaching.
