  1. 1. Optimal Force Distribution for Active and Semi-active Suspension Systems

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

    Författare :Gobi Kumarasamy; [2022]
    Nyckelord :Optimisation; Semi-active suspension system; Primary and secondary ride; Skyhook controller; Force allocation algorithm; Arbitration error; Optimering; Semiaktivt fjädringssystem; Primär och sekundär åkkomfort; Skyhook-styrenhet; Force-allokering algoritm; Arbitreringsfel;

    Sammanfattning : The development needs of handling and ride vehicle dynamic characteristics are constantly evolving, crucial for safety and comfortable commute since many active safety and driver assistance systems depend on these characteristics. Ride improvements enhance passenger comfort, which plays a significant role in quality and brand value. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. Semi-active suspension seats in High speed crafts

    Master-uppsats, KTH/Marina system

    Författare :Victor Ekström; [2019]
    Nyckelord :;

    Sammanfattning : The working environment of a high-speed-craft (HSC) can be uncomfortable and hazardous for the crew and passengers on board. This due to the repeated exposure to high levels of vibration and shocks, that can lead to reduced performance and severe injuries to the back and neck. LÄS MER

  7. 5. Terrain sensor for semi active suspension in CV90

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Datavetenskap

    Författare :Fredrik Nordin; [2017]
    Nyckelord :terrain sensor; cv90; slam; visual odometry; kinect; suspension; lidar; flir; lwir;

    Sammanfattning : The combat vehicle, CV90 has a semi-active hydraulic suspension system which uses inertial measurements for regulation to improve accessibility. To improve performance further measurements of future terrain can be used to, for example, prepare for impacts. LÄS MER
