  1. 1. Centralized motion control of gas-hydraulic suspension on e-bus

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robin Rutström Kugel; [2022]
    Nyckelord :;

    Sammanfattning : Most modern heavy vehicles use pneumatic suspension systems to adjust the height and stiffness of thesuspension by inflating or deflating air bellows with compressed air. The pneumatic suspension system hasbeen advantageous to use, even though the required components are bulky, because of the versatility thatthe pneumatic systems provide. LÄS MER

    Sammanfattning : Passenger ride vibration comfort is a critical aspect to consider while developing any vehicle and there is a need to understand how the occupants would be affected when driving on different road profile roughness. Hence, road profile generation is critical as road profiles are used as inputs to simulation tools to investigate vehicle dynamic behaviour in depth. LÄS MER

  4. 3. Traffic Simulation of Automated Shuttles in Linköping University Campus

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Rihanna Gugsa Gebrehiwot; [2021]
    Nyckelord :automated shuttles; microscopic traffic simulation; car-following models; IDM; Krauss; SUMO.;

    Sammanfattning : Automated shuttles are designed to provide a clean transportation and improve access to areas such as where travelers have to walk long distances to/from bus stops. The introduction of automated shuttles in the road network might affect the safety of pedestrians and cyclists as well as traffic performance of motorized vehicles. LÄS MER

  5. 4. Truck electrification : Trends and impacts on the energy system

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

    Sammanfattning : In line with the Paris agreement, Sweden has set up a national emission reduction target for the transport sector; to reduce the emissions by 70% by 2030, relative to levels in 2010. This entails that large shares of road transport will be electrified, including shares of the national truck fleet. LÄS MER

  7. 5. Strategies for Road Profile in Adaptive Suspension Control

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Fredrik Skoglund; [2020]
    Nyckelord :;

    Sammanfattning : Semi-active suspension systems has become an increasingly popular alternative to the passive suspensions in recent time. By varying the spring stiffness and damping coefficient in the system, different characteristics can be achieved depending on driver preferability and road disturbances. LÄS MER
