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. Research and Analysis of Suspension Dynamics of an Autonomous Bidirectional Road Vehicle

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

   Författare :Isabelle Gürsac; Tsimafei Klimantovich; [2023]
   Nyckelord :Bidirectional vehicle; 4WS; 4WD; suspension angles; kingpin inclination; camber angle; caster angle; toe angle; relative importance; suspension setup; suspension system; drivetrain; efficiency.; Dubbelriktat fordon; fyrhjulsstyrning; fyrhjulsdrift; hjulvinklar; Kingpin-lutningsvinkel; cambervinkel; castervinkel; toevinkel; relativ betydelse; fjädringsinställning; hjulupphängningssystem; drivlina; effektivitet.;

   Sammanfattning : The bidirectionality of road vehicles is a novel research area, which is directly connected with autonomy, efficiency, flexibility and sustainability of transportation. The research in this area is mostly performed with stringent restrictions in corporate secrecy. This fact makes the area publicly unexplored, moreover highly future oriented. LÄS MER

4. 3. 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

5. 4. 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.
