  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. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Guillaume Larrat; [2023]
    Keywords : Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

    Abstract : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. READ MORE

  4. 3. Dynamic Modelling of a Fluidic Muscle with a Comparison of Hysteresis Approaches

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tess Antonsson; [2023]
    Keywords : Mechatronics; Soft Actuators; Pneumatic Artificial Muscles; Dynamic Modelling; Hysteresis; Maxwell-Slip Model; Generalised Bouc-Wen Model; Mekatronik; Mjuka Ställdon; Pneumatiska Artificiella Muskler; Dynamisk Modellering; Hysteres; Maxwell-Slip Modell; Generaliserad Bouc-Wen Modell;

    Abstract : n recent years, there has been a surge in interest and research into the utilisation of soft actuators within the field of robotics, driven by the novel capabilities of their inherently compliant material. One such actuator is the Pneumatic Artificial Muscle (PAM) which offers a high power-to-mass ratio, compliance, safety, and biological mimicry when compared to their traditional counterparts.

  5. 4. CFD Analysis of the Flow Around a Paraglider Wing

    University essay from KTH/Teknisk mekanik

    Author : Caterina Gennari; [2023]
    Keywords : Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

    Abstract : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. READ MORE

  6. 5. Glued connection for TCC slabs : Experimental and Numerical investigation

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Ervin Halilovic; Seid Lotinac; [2022]
    Keywords : TCC connection; Composite element; Adhesive connection; Silicone Adhesive; Polyurethane Adhesive; Slip modulus; Shear stress; Cohesive elements; Traction seperation law; Mullins effect; Hysteresis;

    Abstract : Timber-concrete composite (TCC) structures are becoming more popular in several industrial applications as an efficient method for optimizing the structural performance and the cost of construction as well as lowering the emissions of carbon dioxide. TCC floors are more sustainable than pure concrete floors and more resistant to vibrations and excessive deflections than pure wooden floors. READ MORE
