Dual Quaternion Variational Integrator for Rigid Body Dynamic Simulation
Xu, Jiafeng; Halse, Karl Henning (Research report, 2016)In rigid body dynamic simulations, often the algorithm is required to deal with general situations where both reference point and inertia matrix are arbitrarily de- fined. We introduce a novel Lie group variational integrator ... -
Dynamic Simulation and Control of an Active Roll Reduction System Using Free-Flooding Tanks With Vacuum Pumps
Xu, Jiafeng; Ren, Zhengru; Li, Yue; Skjetne, Roger; Halse, Karl Henning (Journal article; Peer reviewed, 2018)Ship roll motion is critical for offshore operations due to its lack of damping mechanism. This paper demonstrates a dynamic simulation scheme of an active roll reduction system using free-flooding tanks controlled by ... -
Dynamic Simulation and Control of an Active Roll Reduction System Using Free-Flooding Tanks With Vacuum Pumps
Xu, Jiafeng; Ren, Zhengru; Li, Yue; Skjetne, Roger; Halse, Karl Henning (Chapter; Peer reviewed, 2017)Ship roll motion is often the critical factor for offshore operations due to its lack of damping mechanism. This paper demonstrates a dynamic simulation scheme of an active roll reduction system using free-flooding tanks ...
