About Terje Rølvåg
Background.
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. Between 2003-2019 he had a full time professor position at the NTNU/MTP Engineering Design group. Rølvåg is currently teaching at NTNU / Department of Ocean Operations and Civil Engineering
Research Fields.
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). Since 2017, Rølvåg has developed and applied this technology in real time Digital Twin implementations for Condition (CM) and Structural Health Monitoring (SHM) of machinery, drivelines, bridges, windmills, radar, weapon and robot systems. Rølvåg is in charge of several IoT / Digital Twin courses and imlementation projects at NTNU, OSLOMET and SINTEF OCEAN.
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 appliying the lean principles in Configure (CM) and Engineer To Order (ETO) projects for automated design and manufacturing of customized products for SMEs.
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.
Teaching:
- IP500520 - Digital Twin Technologies for Condition and Structural Health Monitoring https://www.ntnu.edu/studies/courses/IP500520#tab=omEmnet
- TMM4155 - Finite Element Applications in Mechanical Engineering (http://www.ntnu.edu/studies/courses/TMM4155#tab=omEmnet) (video lectures only)
Rølvåg also supervise master students in structural, thermal, control and mechanism analysis within the automotive, offshore, robotics, windmills, defense and aerospace industries. This work include a wide range of CAE tools like NX, Nastran, Abaqus and FEDEM
