  1. 1. Active and semi-active suspensions for articulated vehicles to minimise tyre wear

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

    Författare :Haoran Zhang; [2021]
    Nyckelord :Articulated vehicle; tyre wear; quarter car model; semi-active and active suspension; Ledat fordon; däckslitage; kvartsbilsmodell; semiaktiv och aktiv fjädring;

    Sammanfattning : Tyre wear is a vital problem in vehicles, especially in articulated vehicles because of their heavier axle loads. Tyre wear can not only do harm to vehicle dynamics but also cause tyre particle emissions. Therefore, solutions that can minimise tyre wear are where this thesis work focuses. LÄS MER

  3. 2. Investigation of the comfort improvements by an integrated chassis control strategy

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

    Författare :Zhaohui Ge; [2021]
    Nyckelord :comfort; active suspension; active anti-roll bar; active rear-wheel steering; torque vectoring; model predictive control; komfort; aktiv fjädring; aktiv krängningshämmare; aktiv bakhjulsstyrning; drivmomentvektorisering; modellprediktiv reglering;

    Sammanfattning : Autonomous driving is one of the megatrends in today’s automotive industry. Passengers are expected to do more non-driving tasks in an autonomous driving vehicle. Therefore, the comfort of the vehicle has become a more important factor for the passengers. LÄS MER

  4. 3. Test and refinement of a down-scaled actively suspended forwarder

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Qingxiao An; [2016]
    Nyckelord :Scaled vehicle; pendulum arm suspension; rough ground test; Nedskalat fordon; pendelarmsfjädring; ojämn mark; provning;

    Sammanfattning : Cut-To-Length (CTL) logging is the dominating logging method in many parts of the world. CTL logging requires a forwarder for the logs from the felling area to a landing area. Due to the harsh off-road working conditions, a well performed suspension system is necessary for the forwarder. LÄS MER

  5. 4. Heterogeneous MBS forwarder modeling and co-simulation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Liunan Yang; [2015]
    Nyckelord :Co-simulation; ADAMS; MATLAB Simulink; Forwarder; Active suspension; Pendulum arm; ADAMS; MATLAB Simulink; Skotare; Aktiv fjädring; Pendelarmar;

    Sammanfattning : The forwarder acts as an important role in mechanized Cut-to-Length timber harvesting system. But the majority of forwarder products on the market are not suspended or simply suspended by bogies which limit the riding quality of forwarder and result in soil damage due to large tireground interaction force.

  7. 5. Development of an active suspension control strategy for a forestry machine with pendulum arms

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Jorge Aguilar; Morgan Viktorsson; [2014]
    Nyckelord :;

    Sammanfattning : The forest industry depends on the cut to lenght method for production. The forwarder is one of the machines used in this process. These machines currently have no suspension, which leads to big problems such as lower productivity and higher soil damage. LÄS MER
