  1. 1. Evaluating the performance of cone crushers under various feeding conditions using DEM and coupled DEM-MBS simulations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :John Larsson; [2023]
    Nyckelord :Discrete Element Method; DEM; Cone Crusher; Segregation; Co-Simulation; Multi-body Dynamics; MBD;

    Sammanfattning : Cone crushers are used in both the construction and mining industries for the production of aggregates and extraction of ores. Aggregates are used when building for example houses, roads and railways, hence the cone crushers are a vital part of modern society. LÄS MER

  3. 2. Multibody simulations of vibrations in a truck’s steering system

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Marcus Didenbäck; [2023]
    Nyckelord :Multibody simulation; Vibrations; Stiff differential equations; Equations of motion; Lagrange; Vehicle dynamics; Adams; Flerkroppssimulering; Vibrationer; Styva differentialekvationer; Rörelseekva-tioner; Lagrange; Fordonsdynamik; Adams;

    Sammanfattning : This thesis aims to explore if multibody simulations is a suitable method to investigate vibrations in the steering system of trucks. Vibrations in the steering system and subsequently in the steering wheel is a common issue that automotive manufacturers face. LÄS MER

  4. 3. Comparing Four Modelling Methods for the Simulation of a Soft Quadruped Robot

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karin Lagrelius; [2022]
    Nyckelord :Soft Robotics; Modelling; Simulation; Lumped-parameter-method; Quadruped; Soft Actuator; Matlab Simulink; Matlab Simscape Multibody; Mjuk robotik; Modellering; Simulering; Klumpparametermetoden; Fyrfota; Mjukt ställdon; Matlab Simulink; Matlab Simscape Multibody;

    Sammanfattning : A soft quadruped robot is being developed at the Department of Machine Design and Department of Production Engineering at KTH. The legs of the robot consist of four continuum actuators that can achieve complex movements. In order to efficiently develop gaits for the robot, reinforcement learning will be used. LÄS MER

  5. 4. Evaluating the roll performance of a hydraulic-interconnected suspension system for an electric bus

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Dinesh Ramachandran; [2021]
    Nyckelord :Electric bus; Centre of Gravity; Roll gradient; Hydro-pneumatic suspension; Multi-body simulations; Co-simulation; Elektrisk buss; Tyngdpunkt; krängningsgradient; Hydro-pneumatisk fjädring; Flerkroppssimuleringar; Co-simulering;

    Sammanfattning : Electric buses often have batteries installed on the roof structure to have a better space utilization. This increases the height of the centre of gravity of the vehicle, affecting its roll stability. The existing vehicle setup uses an anti-roll bar to provide the roll stiffness. LÄS MER

  7. 5. Modelling of contacts in Adams flex bodies using Mamba

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Shashwat Joshi; [2021]
    Nyckelord :Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

    Sammanfattning : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. LÄS MER
