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. Evaluation of Active Rear Steering through Multi-Body Simulation

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

   Författare :Matteo Rossi; Gabriele Bertoli; [2021]
   Nyckelord :Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

   Sammanfattning : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

4. 3. Enhancement of evaluation method of journal bearings’ performance in heavy-duty diesel engines

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

   Författare :Sateesh Nataraj; [2021]
   Nyckelord :Asperity contact pressure; elastohydrodynamic lubrication; friction; flow factors; run-in wear profile; Asperitetskontakttryck; elastohydrodynamik; friktion; flödesfaktorer; slitageprofil efter inkörning;

   Sammanfattning : Journal bearings are being used in various locations of an internal combustion engine. They contribute to a large portion of total engine friction and lowering it means a significant contribution to CO2 reduction. LÄS MER

5. 4. Control Implementation and Co-simulation  of A 6-DOF TAU Haptic Device

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

   Författare :Yang Zhang; [2020]
   Nyckelord :Co-simulation; Haptic rendering; Multi-body simulation MBS ; Parallel robot; Samsimulering; Haptisk rendering; Multi-body simulation MBS ; Parallell robot;

   Sammanfattning : In the research area of virtual reality, the term haptic rendering is defined as the process of computing and generating the interaction force between the virtual object and the operator. One of the major challenges of haptic rendering is the stably rendering contact with a stiff object. LÄS MER

7. 5. Modelling of Automotive Suspension Damper

   Master-uppsats, KTH/Fordonsdynamik

   Författare :Saurabh Vyas; Venkata Dinesh Raju Jonnalagadda; [2020]
   Nyckelord :Damper Model; hysteresis; least squares fitting; Stribeck friction model; Parameterization; FV curve; Damper test rig; Error matrix; Error plots; Multibody Simulation; MBS.; stötdämparmodell; hysteres; minsta kvadratpassning; Stribeck-friktionsmodell; Parametrisering; FV-kurva; stötdämpartestrigg; Felmatris; Feldiagram; Flerkroppssimulering; MBS;

   Sammanfattning : A hydraulic damper plays an important role in tuning the handling and comfort characteristicsof a vehicle. Tuning and selecting a damper based on subjective evaluation, by considering theopinions of various users, would be an inefficient method since the comfort requirements of usersvary a lot. LÄS MER
