  1. 1. Dynamic Modelling of the KTH Roller Rig

    Master-uppsats, KTH/Spårfordon

    Författare :Daniele Mario Fraschini; [2021]
    Nyckelord :rail vehicle dynamics; roller rig; scaling; track irregularities; validation; modelling; spårfordons dynamik; rullrigg; nedskalning; spårlägesfel; validering; modellering;

    Sammanfattning : The Rail Vehicle Research group at Kungliga Tekniska Högskolan (KTH) is on the path to design and build a scaled test rig called roller rig for research and educational purposes. A roller rig is a device simulating the track with rollers on which the test subject (a wheelset, bogie or even a full vehicle) canbe placed. LÄS MER

  3. 2. Acoustic Radiation Of An Automotive Component Using Multi-Body Dynamics

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Shayan Aghaei; [2020]
    Nyckelord :NVH; Acoustic Simulation; Multibody Dynamics; Automotive;

    Sammanfattning : An important facet of creating high-quality vehicles is to create components that are quiet and smooth under operation. In reality, however, it is challenging to measure the sound that some automotive components make under load because it requires specialist facilities and equipment which are expensive to acquire.

  4. 3. A deformable terrain model in multi-domain dynamics using elastoplastic constraints: An adaptive approach

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Simon Agvik; [2015]
    Nyckelord :deformable terrain model; real-time simulations;

    Sammanfattning : Achieving realistic simulations of terrain vehicles in their work environment does not only require a careful model of the vehicle itself but the vehicle's interactions with the surroundings are equally important. For off-road ground vehicles the terrain will heavily affect the behaviour of the vehicle and thus puts great demands on the terrain model. LÄS MER

  5. 4. Multi-objective optimization and performance evaluation of active, semi-active and passive suspensions for forestry machines

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Federico Baez; [2014]
    Nyckelord :Forestry machine; suspension; multi-objective optimization; forwarder; pendulum arm; active; semi-active; passive; XT28; Multibody Dynamics; soil-friendly; off-road; Skogsmaskin; fjädring; optimering; skotare; pendelarm; aktiv; semi-aktiv; passiv; XT28; flerkroppsdynamik; markvänlig; off-road;

    Sammanfattning : The development of forestry machines is currently heading towards new solutions that reduce their impact on the environment and in particular on the soft forest soil in which the machines operate. The terrain conditions that forestry machines encounter in their regular duties can be very rough, and if the vehicle-ground interaction is not properly controlled cumulative damage can progressively aggravate these conditions and potentially render a route or a zone impracticable, apart from causing a detrimental effect in the forest environment.
