1. 1. Propulsion modelling of a generic submarine propeller

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gustav Boman; [2023]
   Keywords : OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

   Abstract : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. READ MORE

3. 2. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Mats Vesterberg; [2022]
   Keywords : EMA; Electromechanical Actuator; Linear Actuator; Shock load; Protection mechanism; Elektromekaniska ställdon; Linjära ställdon; Shocklaster; Överlastskydd;

   Abstract : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. READ MORE

4. 3. Learning-Based Motion Planning and Control of a UGV With Unknown and Changing Dynamics

   University essay from Linköpings universitet/Reglerteknik

   Author : Åke Johansson; Joel Wikner; [2021]
   Keywords : machine learning; model predictive control; motion planning; Bayesian linear regression; motion primitives; input sampling; hybrid A*;

   Abstract : Research about unmanned ground vehicles (UGVs) has received an increased amount of attention in recent years, partly due to the many applications of UGVs in areas where it is inconvenient or impossible to have human operators, such as in mines or urban search and rescue. Two closely linked problems that arise when developing such vehicles are motion planning and control of the UGV. READ MORE

5. 4. Semi-Automatic Generation of Control Law Parameters for Generic Fighter Aircraft

   University essay from Linköpings universitet/Reglerteknik

   Author : Markus Lindblom; [2020]
   Keywords : Semi-automatic; control; law; generic; fighter; aircraft;

   Abstract : Control law design can be an iterative and time-consuming process. The design procedure can often include manual tuning, not uncommonly in the form of trial and error. Modern software tools may alleviate this process but are generally not developed for use within any specific industry. READ MORE

6. 5. Multi-Objective Optimization of Torque Distribution inHybrid Vehicles

   University essay from KTH/Fordonsdynamik

   Author : Ansh Gandhi; Ankur Fartyal; [2020]
   Keywords : ;

   Abstract : Electrification is one of the mega-trends in the transportation and automotive industry today. Boththe alarming environmental conditions and the ever decreasing fuel reserves are driving the shifttowards hybrid, all electric and alternative fuel source vehicles. READ MORE
