  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

  3. 2. Evaluating the roll performance of a hydraulic-interconnected suspension system for an electric bus

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

    Författare :Dinesh Ramachandran; [2021]
    Nyckelord :Electric bus; Centre of Gravity; Roll gradient; Hydro-pneumatic suspension; Multi-body simulations; Co-simulation; Elektrisk buss; Tyngdpunkt; krängningsgradient; Hydro-pneumatisk fjädring; Flerkroppssimuleringar; Co-simulering;

    Sammanfattning : Electric buses often have batteries installed on the roof structure to have a better space utilization. This increases the height of the centre of gravity of the vehicle, affecting its roll stability. The existing vehicle setup uses an anti-roll bar to provide the roll stiffness. LÄS MER

  4. 3. Development and testing of controller that introduces the functionality to lift the second front axle on a heavy vehicle

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mattias Vikgren; [2021]
    Nyckelord :PI control; Bang-bang control; Simulation; Suspensions; Pneumatic actuators.; PI regulator; Bang-bang regulator; Simulering; hjulupphängningar; Pneumatiska ställdon.;

    Sammanfattning : The transition to more environmentally sustainable transports, as well as rising fuel prices create a demand for efficient means of transportation. Liftable axles have shown potential to save fuel and reduces tire wear on heavy vehicles. LÄS MER

  5. 4. Hydropneumatic suspension in a truck : Installation of a hydropneumatic suspension for a Scania truck

    Kandidat-uppsats, Karlstads universitet

    Författare :Rasmus Karlqvist; [2020]
    Nyckelord :hydropneumatic suspension; Scania CV AB; air springs; air suspension; brackets; installation;

    Sammanfattning : Investigation and testing of hydropneumatic suspension systems has previously been done at Scania between the year 1992 and 2000. Interest has aroused at Scania CV AB to further test a hydropneumatic suspension. The reason being the new ventures of decarbonised, clean, electrified, automatized and digitalised vehicles. 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
