1. Finite element modelling of hydroelasticity in hull-water impacts
Sammanfattning : The work in this thesis focuses on the use of explicit finite element analysis (FEA) in the modelling of fluid-structure interaction of panel-water impacts. Paper A, considers modelling of a two-dimensional rigid wedge impacting a calm water surface. LÄS MER
2. Hydroelasticity in Marine Hull Bottom Panels - Modeling and Characterization
Sammanfattning : The work in this thesis is concerned with the localized problem of hydroelasticity in marine panel-water impacts with an overall aim to increase the efficiency of high-speed craft by application of more refined methods in the structural design. The work mainly focuses on numerical modeling of the hydroelastic problem and therewith related aspects in the modeling and characterization of hydroelasticity. LÄS MER
3. Hydrobatics: Efficient and Agile Underwater Robots
Sammanfattning : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Hydrobatic capabilities in autonomous underwater vehicles (AUVs) can enable increased maneuverability without a sacrifice in efficiency and speed. This means innovative robot designs and new use case scenarios are possible. LÄS MER
4. Hydrobatics: Real-time Control, Simulation and Learning for Underactuated AUVs in Agile Maneuvers
Sammanfattning : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Underwater robots such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) are either designed as flight style, optimized for range and speed, or hover style, optimized for precise maneuverability.
