  1. 1. Dynamic Modelling of a Fluidic Muscle with a Comparison of Hysteresis Approaches

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

    Författare :Tess Antonsson; [2023]
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Integration of Open Data in Disaggregate Transport Modelling : A Case Study of Uppsala

    Master-uppsats, KTH/Transportplanering

    Författare :Iqbal Surahman; Gustav Wegner; [2022]
    Nyckelord :Agent-based; Disaggregate Transport Model; Open Data; OpenStreetMap; OSM; GTFS; Agentbaserad; Disaggregerad Transportmodell; OpenData; OpenStreetMap; OSM; GTFS;

    Sammanfattning : Transport models are key in predicting travel behaviour and planning transport systems. Transport models can be either aggregated or disaggregated. Disaggregation means that travel behaviour is represented on an individual level, which can be beneficial because it offers a higher detail level and reduces aggregation bias. LÄS MER

  4. 3. Two-phase CFD Modelling and Validation : SH204X Master Thesis Project Report

    Master-uppsats, KTH/Kärnenergiteknik

    Författare :Richard Härlin; [2022]
    Nyckelord :Master Thesis; Simulation; Validation; DEBORA; CFD; OpenFOAM; Boiling; Two-phase Thermal-Hydraulics; Fluid Mechanics; Nuclear Power Safety; Examensarbete; Simulering; Validering; DEBORA; CFD; OpenFOAM; Kokning; Tvåfas Termohydraulik; Kärnkraftssäkerhet;

    Sammanfattning : This project deals with two-phase CFD model validation, a subject which is currently under active research due to its complexity. The goal is to create a model that predicts data profiles to an acceptable degree for a wide array of flow conditions. The applications within the nuclear field would mainly be for safety analysis, e.g. LÄS MER

  5. 4. Validation of an implementation of MBSE and the possibility of Simulating System Models

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Yasmin Chaoui El Kaid; [2021]
    Nyckelord :;

    Sammanfattning : Model-Based Systems Engineering (MBSE) is the process of developing a set of system models that help define, design and document a system under development. These models provide an efficient way to explore, update, and communicate system perspectives to stakeholders, while eliminating dependence on traditional documents. LÄS MER

  7. 5. Improving the validation of a railway vehicle model in the virtual certification process

    Master-uppsats, KTH/Spårfordon

    Författare :Bente de Leeuw; [2021]
    Nyckelord :Rail vehicle dynamics; Rail vehicles; Rail profiles; wheel profiles; model validation; Dynamik; järnvägsfordon; järnvägsprofiler; hjulprofiler; modellvalidering.;

    Sammanfattning : Before vehicles can be placed in service it has to complete an authorisation process. At the moment,this process is largely depended on tests. This is, however, an expensive and long process. With new technologies and improved simulations this process can be shortened and the costs can be lowered. LÄS MER
