Lifetiime analysis and testing of silent tools damping system
(Master thesis, 2011)Dynamiske tester ble gjennomført for tre forskjellige materialer ved forskjellige temperaturer og frekvenser. Materialer som ble testet er 40shore, 60shore og 90shore EPDM gummi. Disse er vanlig brukt i dempesystemet som ... -
Lifetime assessment and optimization of a welded a-type frame in a mining truck considering uncertainties of material properties and structural geometry and load
(Peer reviewed; Journal article, 2019)In order to improve the fatigue performance of a welded A-type frame in a heavy off-road mining truck, a novel method was presented to implement lifetime and weight collaborative optimization while considering uncertainties ... -
Lift Control of Adaptive Wind Turbine Blades with Bend-Twist Coupling
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:215, Doctoral thesis, 2014)A major challenge in the development of wind turbines comes with designing the blades so that they are robust, low weight, cost effective and highly efficient. As the industry develops and as more turbines are built in ... -
Lifting sustainable food science from lab to industry: An experimental study and development of a Soluble Gas Stabilisation (SGS) flow concept using low-cost off-the-shelf components
(Master thesis, 2023)Bærekraftsspørsmål er viktige for designinteressenter. Mattrygghet er avgjørende for menneskers helse og en betydelig bidragsyter til klimaendringer. Matsvinn og emballasjebruk er problemer i dagens matindustri. En potensiell ... -
Line-focus solar concentration 10 times higher than the 2D thermodynamic limit
(Peer reviewed; Journal article, 2022)Line-focus solar concentrators have traditionally been limited by the 2D concentration limit due to the continuous translational symmetry in these systems. This limit is orders of magnitude lower than the 3D limit, severely ... -
