Dynamics of luffing motion of a flexible knuckle boom crane actuated by hydraulic cylinders
Cibicik, Andrej; Pedersen, Eilif; Egeland, Olav (Journal article; Peer reviewed, 2020)In this paper we present a modeling procedure for a flexible knuckle boom crane, which is actuated by hydraulic cylinders and is modeled as a planar multibody system. We propose a convenient framework where both rigid body ... -
Identification of the geometric design parameters of propeller blades from 3D scanning
Njaastad, Eirik B; Steen, Sverre; Egeland, Olav (Peer reviewed; Journal article, 2022)This paper presents a new method for the identification of geometric design parameters of ISO 484 class propeller blades from scanned point cloud data. The method can be used for tolerance inspection and in-line measurement ... -
Numerical study on buckling of aluminum extruded panels considering welding effects
Wang, Xintong; Amdahl, Jørgen; Egeland, Olav (Peer reviewed; Journal article, 2022)Aluminum extruded panels are increasingly used in marine structures as lightweight solutions. Less welding is needed for such extrusions than traditional built-up panels of welding stiffener to plate sheets. However, the ... -
An Open-Source Python-Based Boundary-Element Method Code for the Three-Dimensional, Zero-Froude, Infinite-Depth, Water-Wave Diffraction-Radiation Problem
Viswanathan, Savin; Holden, Christian; Egeland, Olav; Greco, Marilena (Journal article; Peer reviewed, 2021)In this paper, a new open-source implementation of the lower-order, 3-D Boundary Element Method (BEM) of solution to the deep-water, zero Froude-number wave-body interaction problem is described. A validation case for ...
