  1. 1. Numerical simulations on passenger vehicles equipped with a cover under transportation

    H-uppsats,

    Författare :Jaime Mateo Barroso; [2019-07-03]
    Nyckelord :Transport; Grundläggande vetenskaper; Hållbar utveckling; Strömningsmekanik och akustik; Transport; Basic Sciences; Sustainable Development; Fluid Mechanics and Acoustics;

    Sammanfattning : The concern of the car companies to offer an image of quality to their clients has led to take care of every single detail. An example of this, is that newly produced cars are now being covered during their transportation on trucks. The design of the covers involve several wind tunnel tests for each new car model.

  3. 2. Sheet Metal Forming Simulations with Elastic Dies: Emphasis on Computational Cost

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Sara Allesson; [2019]
    Nyckelord :Elastic Sheet Metal Forming Simulation; Computational Cost; Decomposition; LS-DYNA; Elastisk plåtformningssimulering; beräkningskostnad; dekomposition; LS-DYNA;

    Sammanfattning : The car industry produces many of their car parts by using sheet metal forming, where one of the most time-consuming phases is the development and manufacturing of new forming tools. As of today, when a new tool is to be evaluated in terms of usability, a forming simulation is conducted to predict possible failures before manufacturing. LÄS MER

  4. 3. A Weak Formulation of Constraints to Couple Rigid and Elastic Bodies - a Study with FEniCS

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Axel Södersten; [2018]
    Nyckelord :Flexible multibody dynamics; differential-algebraic equations; interconnecting rigid joints; Mathematics and Statistics; Technology and Engineering;

    Sammanfattning : Many complex mechanical systems are simplified by considering them as multibody systems. In recent years, flexible multibody dynamics has become more and more in demand. LÄS MER

  5. 4. Terramechanics based wheel-soil model in a computer game enviroment

    Magister-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Viktor Knutsson; [2016]
    Nyckelord :wheel-soil; terramechanics; GPGPU;

    Sammanfattning : This thesis aimed to develop deformable a virtual terrain which a vehicle can move in and interact with in a realistic manner. The theory used to calculate how the terrain influences the vehicle is based on terramechanics. The terrain is divided into two separate parts, one for visualization and one for physical collisions.

  7. 5. Visual Tracking

    Master-uppsats, Datorseende; Tekniska högskolan

    Författare :Martin Danelljan; [2013]
    Nyckelord :Tracking; Computer Vision; Person Tracking; Object Detection; Deformable Parts Model; Rao- Blackwellized Particle Filter; Color Names;

    Sammanfattning : Visual tracking is a classical computer vision problem with many important applications in areas such as robotics, surveillance and driver assistance. The task is to follow a target in an image sequence. The target can be any object of interest, for example a human, a car or a football. LÄS MER
