Dynamic behaviour of existing and new railway catenary systems under Norwegian conditions
(Doctoral theses at NTNU;2016:298, Doctoral thesis, 2016)This thesis concerns the dynamic behaviour of railway catenary systems, particularly Norwegian systems. The aim of this PhD study is to increase the knowledge of the dynamic behaviour of these systems. This includes analyses ... -
Dynamic behaviour of floating bridges exposed to wave excitation A numerical and experimental investigation
(Doctoral theses at NTNU;2017:365, Doctoral thesis, 2017)By utilizing the buoyancy of the water in a crossing, floating bridges may provide permanent road links where other bridge types would be impossible or too costly to build. Still, floating bridges are not wide-spread in ... -

Dynamic buckling of end anchored floating bridges
(Master thesis, 2018)The Bjørnafjord bridge is a floating bridge planned to be a part of The Norwegian Public Roads Administrations ferry-free road project along E39. This thesis looks into the dynamic behavior of this bridge, focusing of ... -
Dynamic comparison of a railway catenary section upgrade by field measurement assessments
(Journal article; Peer reviewed, 2017)The pantograph-catenary interaction is crucial for running trains on electrical railway lines. The coupled dynamic problem of an in space stationary system, the catenary system, and a system in motion, the pantograph, is ... -
Dynamic Identification and Modelling of a Pantograph
(Master thesis, 2018)The main objective of this thesis is to measure and determine the dynamic properties of a measurement pantograph, and then create a numerical model with the same properties. The purpose of the model is to give a better ... -
Dynamic impact of heavy long vehicles with equally spaced axles on short-span highway bridges
(Journal article; Peer reviewed, 2018)Extremely large trucks with a weight exceeding the standard require a permit before they are allowed to cross the bridges of a specific route. For the purpose of safety, an escort is often ... -
Dynamic Modelling and Analysis of Submerged Floating Tunnels
(Master thesis, 2012)Investigations are performed on the capabilities of Computational Fluid Dynamics (CFD) to model a transient transcritical flow around a Submerged Floating Tunnel (SFT). The aim of this inquiry is to examine the possibility ... -
Dynamic optimization of railway catenary system by turning unwanted lumped-mass into tuned-mass
(Chapter, 2017)The railway catenary is suspended to its supports with droppers, clamps and oth-er fittings. These lumped-masses are made light and small to minimize disturbances. The mass-es cannot be completely removed but can be adjusted ... -
Dynamic Parameter Investigation of a Full Scale Laboratory Overhead Contact Line Section Model
(Master thesis, 2015)In the dynamic parameter investigation of a full scale laboratory section model of a overhead contact line, the effects of tension force and the effect of removing a dropper is of interest. The thesis present the results ... -
Dynamic Performance of High-Speed Railway Overhead Contact Line Interacting With Pantograph Considering Local Dropper Defect
(Peer reviewed; Journal article, 2020)The local dropper defect is the most common fault in the early service stage of the overhead contact line (OCL) system. The plastic deformation and loose of a dropper may cause the variation of the contact line height, ... -

(Master thesis, 2017)This thesis presents dynamic response and fatigue analyses of several bottom-mounted offshore wind turbine models, simulated in the aero-hydro-servo-elastic simulation tool FAST v8. A 5 MW offshore wind turbine supported ... -
Dynamic Response of a Floating Bridge Structure
(Chapter; Peer reviewed, 2016)A theoretical overview of the stochastic dynamic analysis of a floating bridge structure is presented. Emphasis is on the wave-induced response and the waves on the sea surface are idealized as a zero mean stationary ... -
Dynamic response of a multi-span suspension bridge with floating pylons
(Master thesis, 2017)The Norwegian Public Roads Administration is currently investigating the possibility of crossing the 500 m deep and 5 km wide fjord, Bjørnafjorden, located in Norway. Several concepts have been developed on behalf of the ... -
Dynamic Response of an End-Supported Pontoon Bridge due to Wave Excitation: Numerical Predictions versus Measurements
(Peer reviewed; Journal article, 2021)Herein, numerical predictions of the dynamic response of an existing floating pontoon bridge are compared with the measured dynamic response. Hydrodynamic coefficients that describe the fluid-structure interaction and the ... -
