  1. 1. Method Development & Analysis of Seals using FEM

    University essay from KTH/Maskinkonstruktion

    Author : Lovisa Svanborg Östlin; [2023]
    Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

  3. 2. Design of cooling-air permeable coil support

    University essay from KTH/Hållfasthetslära

    Author : Rozbeh Ghassemi; [2023]
    Keywords : Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

    Abstract : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. READ MORE

  4. 3. Sensorless Control of Synchronous Machines in Python Using Signal Injection : An implementation of a High-Frequency Square-Wave Injection Algorithm on a Linear and Non-Linear Synchronous Machine Model in open-source Software Motulator

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Lundberg; [2022]
    Keywords : High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Abstract : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. READ MORE

  5. 4. Global buckling of subsea pipelines with DEH cable

    University essay from KTH/Hållfasthetslära

    Author : Anders Meurk; [2022]
    Keywords : Solid Mechanics; Global Buckling; Subsea Pipelines; DEH cable; Hållfasthetslära; Global Buckling; Undervattensrörledningar; DEH kabel;

    Abstract : Hydrates, wax, and other fluids forms in cold subsea pipelines which restrict flow of petroleum products during operation. This thesis analyses the global buckling behaviour of subsea pipelines with Direct Electric Heating cables (DEH) through a combination of analytical and FEM simulations. READ MORE

  6. 5. Metal Replacement of Ventilator Baseplate

    University essay from KTH/Hållfasthetslära

    Author : Ludvig Eriksson; [2022]
    Keywords : Mechanics; Solid Mechanics; Construction; FEM; Design; Mekanik; Hållfasthetslära; Hållfasthet; FEM; Konstruktion; Design;

    Abstract : Thanks to advancements in the polymer industry, metal replacement with high performance polymers has become a growing practice in many industries due to the economical, lead time and weight advantages. Getinge AB was interested in introducing metal replacement to the medical technology industry by launching a thesis project to replace the die-cast aluminium in a key structural component of their ventilator products.
