1. 11. Beräkningsmodell för oljekylare

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Lisa Nordling; [2022]
   Nyckelord :Oljekylare; hydraulik; värmeutveckling;

   Sammanfattning : In this thesis, a calculation model for oil coolers has been worked on for Ursviken Technology AB press brakes Optima and Optiflex. Analysis of the theory behind physical phenomena has shown that a series of factors in a hydraulic system give rise to heat increase of hydraulic oil. LÄS MER

3. 12. Operation Oriented Digital Twin of Hydro Test Rig

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Ali Khademi; [2022]
   Nyckelord :Digital Twin; Bayesian Optimiation;

   Sammanfattning : It has become increasingly important to introduce the Digital Twin in additive manufacturing as it is perceived as a promising step forward in its development and a vital component of Industry 4.0. Digital Twin is an up-to-date representation of a real asset in operation. The aim of this thesis is to develop a Digital Twin of a hydro test rig. LÄS MER

4. 13. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Amir Avdic; Kishore-Babu Vejendla; [2022]
   Nyckelord :viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

   Sammanfattning : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it. LÄS MER

5. 14. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Mantas Petrosius; [2021]
   Nyckelord :;

   Sammanfattning : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.

7. 15. Controlling a Hydraulic System using Reinforcement Learning : Implementation and validation of a DQN-agent on a hydraulic Multi-Chamber cylinder system

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :David Berglund; Niklas Larsson; [2021]
   Nyckelord :Gear selection; reinforcement learning; machine learning; DQN; neural network; multi chamber cylinder; Digital hydraulics; hydraulics; Matlab; Simulink; Hopsan; hydraulic system validation;

   Sammanfattning : One of the largest energy losses in an excavator is the compensation loss. In a hydraulic load sensing system where one pump supplies multiple actuators, these compensation losses are inevitable. LÄS MER
