Numerical and experimental study of friction loss in hydrostatic motor
(Journal article; Peer reviewed, 2012)This paper presents a numerical and experimental study of the losses in a hydrostatic motor principle. The motor is designed so that the structural deflections and lubricating regimes between moving surfaces and, subsequently, ... -
Numerical and Experimental Study of Shared Mooring Systems for Prototype Floating Wind Farms
(Doctoral dissertations at the University of Agder;no. 431, Doctoral thesis, 2023)Conventional mooring systems represent a substantial portion of the cost of a floating offshore wind farm (FOWF). The concept of shared mooring was initially proposed to reduce the overall usage of mooring lines and the ... -

On break-away forces in actuated motion systems with nonlinear friction
(Journal article; Peer reviewed, 2017)The phenomenon of so-called break-away forces, as maximal actuation forces at which a sticking system begins to slide and thus passes over to a steady (macro) motion, is well known from the engineering practice but still ... -
