Jussi Sopanen
Professor
Jussi.Sopanen@lut.fi

Research interest of Jussi Sopanen are, in a broader perspective, dynamics and vibration of machinery. More particularly, research is focused on rotor dynamics of high-speed electrical drives, dynamics and control of hybrid electric vehicle drivelines and mechanical design of electrical machines. In addition, Sopanen has experience of modelling and analysis of rolling element bearings as well as multibody system dynamics formulations. Some examples of practical applications that Sopanen has studied during past years are wind power generators, turbocompressors and traction motors for hybrid-electric vehicles. Newest research field is utilization of laser vibrometers in experimental vibration measurements. For that, the research group has a state-of-the-art laboratory equipment comprising a Scanning Laser Doppler Vibrometer (SLVD), a single-point laser vibrometer and rotational vibrometer.

Sopanen has published over 40 refereed journal and conference articles in the field of dynamic system design and simulation. He is a member of editorial board in two scientific journals: Shock and Vibration (Hindawi), Mathematical Problems in Engineering (Hindawi). He has acted as a reviewer for 20 scientific journals and conferences. Majority of his research, i.e. projects and publications, are done in co-operation with other research groups, both internationally and nationally. The research results are also embedded into his teaching.
