  1. 16. Development of a DEM-FEM framework for infrastructure simulations

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Anita Ullrich; [2022-09-20]
    Keywords : ;

    Abstract : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. READ MORE

  3. 17. Evaluation of pretension losses in heated screw joint

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Joel Svensson; [2022]
    Keywords : screw joint; clamping force; thermal load;

    Abstract : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. READ MORE

  4. 18. Design of an Embedded Torque Sensor : Based on Volumetric Strain induced Differential Air Pressure

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Wen Qi; [2022]
    Keywords : Torque; Electronics; Gas sealing; Pressure measurement;

    Abstract : This paper proposes a torque sensor based on the differential air pres- sure measurement method using a new embedded structure. The pro- posed sensor design is an improvement over the previous sensor design. The mechanical sensitivity, resolution, and stress distribution of the new sensor are analyzed by finite element modeling. READ MORE

  5. 19. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fritiof Hegardt; [2022]
    Keywords : Technology and Engineering;

    Abstract : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). READ MORE

  6. 20. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Martin Fajerberg; Mattias Nylander; [2022]
    Keywords : Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Abstract : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. READ MORE
