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. LÄS MER

3. 17. Feasibility Study of Wind Turbine Blades Constructed in 1300 MPa Fossil-Free Steel : Finite Element weight optimization with respect to structural integrity by Abaqus and Tosca Structure

   Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Peter van der Brug; Sina Urban; [2022]
   Nyckelord :Abaqus; Tosca Structure; Wind Turbine Blade; Weight Optimization; High-Strength Steel; Fossil-Free; SSAB; Strenx 1300; DTU 10MW-RWT;

   Sammanfattning : This study aims to perform a feasibility study on the DTU 10MW-RWT wind turbine blades constructed in the fossil-free high-strength steel 1300 MPa from SSAB. The acceptance criteria, on which the study is based, are taken from the DTU composite wind turbine model. A maximum weight of 41 000kg and a maximum tip displacement of 12.5 m are chosen. LÄS MER

4. 18. Lifetime extension of offshore wind farms

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Robert Eriksson; [2022]
   Nyckelord :Lifetime extension; offshore wind power; O M; reliability; ReliaSoft;

   Sammanfattning : Renewable energy sources are in strong demand as the need for clean energy is increasing, driven by the need to reach the environmental targets. Offshore wind power is becoming an attractive source as the technology matures and cost decreases. With time all wind farms age and when the time comes one needs to consider end of life alternatives.

5. 19. Creation of a Finite Element Model andSystem Analysis for the Low and HighFrequency Cryogenic Telescopes of theSpace Mission LiteBIRD

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Matias Rittatore Texeira; [2022]
   Nyckelord :FEM; FEA; mesh model; CMB; IRAP;

   Sammanfattning : The Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection (LiteBIRD) is a Japan Aerospace Exploration Agency (JAXA)-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the early Universe, through the measurement of their imprint onto the polarization of the Cosmic Microwave Background (CMB). It is an international collaboration, with European Union (EU) operations being coordinated by France. LÄS MER

7. 20. Kvinnors rättigheter eller exploatering av kvinnor? Den polariserade prostitutionsdebatten

   Master-uppsats, Göteborgs universitet/Institutionen för litteratur, idéhistoria och religion
